There has been ample knowledgeable advice provided, thus warranting your own investigation. Once you have ascertained your own needs, the decision will be much easier, yet don’t lose focus in achieving a well tuned arrow.
Just an FYI…. My top scores exceeding a ‘9’ at 3D’s this year were with 350 gns up front(565 gn total) and my 3rd highest score was with 400 gns up front( 611 gn total). Good scores are relative and these happened to be nice scores for me and didn’t hurt that they were winners.
I have not fared well when there were many targets over 25 yards. Last weekend there were ~8 targets from ~27 to 32 yards. The arrow drop appears greater than normal beyond 25 yards and in conjunction with my inept skills; the outcome did not bode well.
Note: Just my observation… some may perceive a much greater drop at closer distances since there set-up has not been tuned to that particular arrow and don’t pursue increasing up front weight. And there are those such as myself who have shot EFOC and Ultra-EFOC so long that the trajectory seems perfectly normal. Possibly, if I ventured back to hi FOC or normal FOC, I may notice the difference. Then I may not be happy if my engrained site window is significantly impacted.
You need to determine your own needs first. For me, if my shots were no longer than 15 yards, then I would pile on even more front end wt. relative to the draw wt’s and arrow designs I currently shoot.
Best of luck!

Is this to much weight?
all that matters is how consistently accurate you are with your arrows, how well the arrows fly, that the arrows are no less than 9gpp mass weight, how sharp the broadheads are - all the rest is nearly meaningless.
fwiw, my carbon arrows are 29.5", 300gr up front, 585 grains mass weight outta 50-55# longbows. they do just fine if i do my job well.
It has been my personal experience and conclusions drawn from visiting with others that the reason most archers have trouble with high FOC arrows is they have not taken the time to tune their arrows. Switching to high FOC weights generally requires a change in arrow spine maybe even feather length and height. It is not for everyone mainly because most people do not like change and they are satisfied with their set up .For those that want to learn more about their sport and are not satisfied with status quo, experimenting can be very rewarding Those who hunt and because of age , or injury have had to reduce bow draw weight FOC arrows in the 20% to 30+% allow the hunter to reduce bow weight and still hunt with a extremely lethal arrow. Archers who hunt dangerous game already know the benefits of heavy FOC arrows. The argument that heavy FOC arrows loose trajectory has validity. One has to weigh the advantages over the disadvantages. I believe that in ranges up to 25 yards it does not make any difference .Once one comments to a high FOC arrow they should only practice w1th that set up .If you shoot instinctively your brain adjust and compensates. Most game killed with a traditional bow is under 25 yds. In order to shoot high FOC arrows it does not mean you have to shoot extremely heavy over all weight arrows. New carbon arrows have been developed that are high in spine and not extremely heavy. This allows the archer to place more of his total arrow weight up front and not use extremely heavy arrows which effect trajectory. On company making such arrows is Alaskan Bowhunting Supply a sponsor here on tradgang. There probably other manafctures that I am not aware of. http://www.alaskabowhunting.com/GrizzlyStik-Momentum-Shafts-font-colorf5a50abNEWbfont--C59.aspx I am personally shooting a 750 gn total weight arrow from a 50lb longbow. Of that 750 grain 360 grains are up front. That is with a standard carbon arrow not the new “momentum arrows” If experimenting with FOC visit http://tuffhead.com/education/formulas_FOC.html for a explanation and calculator to help in figuring percent of FOC One should keep in mind FOC is a advantage in soft tissue and may not contribute to penetration of bone. Keeping the total arrow weight above 650 grains will help if metal hits bone
Well call me crazy but I threw on some 175 field points and they seem to fly well(great groups) bow is less noisy and bare shaft seems to group with but lower(nock pt)need to play more later, but up to 25yrds(all I can shoot in back ya rd) seems to work( & goes deeper into target)

Yes...ANYTIME you add weight to an arrow and get it tuned you are going to gain penetration(till you max out your set ups window)....so, its not JUST added FOC....some yes, but more just the addition of the weight itself no matter if its all in the head, the shaft or a combo of both.
Joe, I love your head design and quality....hope to hunt big enough game with them sometime in the future.... and would LOVE to see your version of an el grande
Also....click here if you are interested in the origin of FOC experiments...
You would think that someone with a fixed video camera could take video of different arrows that weighed the same and had drastically different foc and video the trajectory at different distances to really evaluate the difference. I would love to see a graph of that.

I have shot different degrees of FOC up to 32 % and can't see any trajectory difference as long as arrow weights are close.I don't have a chrono right now but it would be interesting to compare speeds from say 30 yds.

I know guys who shoot 525 up front. I agree with Terry however, I myself like between 175 and 250 tops and find I have been shooting 190 grains up front. A 50 grain brass insert and 125 grain broadhead and 15 grain footing. This is what flies best for me out of my .500 spined arrows and the weight of bow I am shooting. I like a pretty flat arrow and I can get any bow quiet without worrying about weighting my arrow, a lil' bowhush and hushpuppies in the right spots and you are good to go! Shawn
