GT 1535 vs 3555 --- More Help Please!!!

[LostNation_Larry]

For the record wood arrow spine is determined on 26" centers and the .600" deflection on carbons is measured on 28" centers.  For wood you use a 2 pound weight but on carbon they use a 1.92 pound weight.

I shoot an RER Retro
49@28 (I draw 27).  Mine likes a CE 90 with standard insert and 175 grain point.   Arrows cut 29 inches.   Riser cut 3/16 past center.

I know for me and my 47lb palmer recurve I shot arrows cut to 28" and the 1535's fly with 125gr points and the 3555's fly with 200grs up front.

[mahantango]

Just leave those 35/55's full length and be prepared to use a lot of point weight. 50 and 100gr. inserts will help. And, I highly recommend bare-shaft tuning them - it will really save you some aggrevation.

[Archer Dave]

Thanks again guys. I went ahead an ordered a dozen 3555 GT Trads.

Then to add to my confusion I started playing with Stu's calculator which seems to indicate maybe I need 5557's? Man am I confused.

The 3555's with a 125gr point and cut 30.5". Seems to be a good match at 9gpp.

   

Then there is the same arrow but with a 50 gr weight added to the insert to get up to 10gpp, but now we are mismatched in spine.

 

Then we have a 5557 set up the same as the last one with a 50 gr weight added to the insert. Now the spine is matched better, but we have an arrow which most people don't recommend.

   

Arg.. So what is right? Should I try to change my order before it ships? Should I stay with the 3555's like in the first picture without any weight added to the insert and only be 9gpp?

What to do? Ahhhh....  

What seemed like an easy thing is getting convoluted. What are your guys thoughts on this? Am I over thinking this?

Thanks a lot,
Dave

Either 3555s or 1535s.  I think 5575s would be way too stiff unless you had a 35 inch draw and tied a cat to the front of the arrow.  I think a lot of the guys that responded liked the 1535 s for your set up.  W your draw and bow I think you may be right on line where either 3555 or 1535 would tune by playing w length and point weight.   Just my opinion.

[Archer Dave]

Cool man thanks. I think the 3555's will be good for me at 28-5/8". The 3555 GT Trads shipped, so that is what I am going to get in a few days.

[motorhead7963]

I told you, you could go nuts trying to do so much math, my friend you are way over thinking this.

[Archer Dave]

Haha, I am done thinking, the 3555's are on their way. Should be hear in a few days.

I'm a wood and aluminum kind'a guy, been shooting them for years. I went out today and shot 60-75 Carbon Express full length. 4" 4 fletch, stock inserts with a 200 gr. field point. My bow is a Stalker Coyote 46# @ 29"..........They flew like darts and from what I think I'm reading, they shouldn't     so what's up??

[Krex1010]

ArcherDave,
I just got a half dozen gt traditional 3555's. I shoots 45# bear Montana.  I have only just started playing with them, I got 50 grain inserts, and then I'll play with point weight and length to find the right setup.  Just an FYI, 3 rivers has these listed as 30" shafts......they are actually 32" shafts.

[Archer Dave]

Thanks, I noticed that in their printed catalog as showing 30". The place I ordered them did have it listed at 32" thought so I was not sure who was right, so that it is good to know.

[TxRuckus]

Well this is interesring...I too have a 45# grizzly and just received my first order of carbon arrows in the mail today. I based my order off of 3 rivers chart and went with the gt5575 as that spine seemed to be in the middle of all the anticipated broad head gr weights I'm likely to use with this bow and my draw length.  I thought I did my homework but I guess it's back to square one.I plan on starting the tunning process tomorrow and now I am VERY curious on the outcome

[Archer Dave]

I will be curious to see how it works out for you. Let me know of your results.

[Alexander Traditional]

I think David that posted above you is going to be very stiff. I have some 5575 that I have cut to 29" and I'm pulling around 28" out of a 54@28. On that set up I've got 326 grains up front and they fly good. I've been thinking of trying some 3555 to see about a lighter set up. I also shoot some CE 150 for about the same weight up front as the GT 5575. I think as others have posted you be fine with 3555 with more point weight or the other with less point weight,but I sure don't think you could make 5575 work.

I'm by no means an expert, but I would definitely start out shooting those shafts full length, hopefull you didn't have them cut.

[BAK]

It all depends on what you feel comfortable with.  I shoot 45 to 50 pounds and found the 35/55 to be too stiff for me.  I don't like or want heavy FOC.  I go with the 15/35 and can get by with 175 grain broad heads with no additional weighting.

[Bladepeek]

BAK, it all depends on the length of the arrow. Carbons stiffen up so fast as they are cut back. I also shoot mostly 43# - 47# and I need 3555s at about 30" with 180 gr (point & insert) up front, or 1535s with 125gr. If I cut another 1/2" off the shaft, they would be too stiff for me too.

[TxRuckus]

Krex, I don't plan on cutting my 5575s down at all. Especially not until I have played around with them for a while with different weight distribution. Just need it to stop raining so I can pull the tarp off the targets and get to work.

[Stump73]

Order a field point test kit.  Theycome 2 point each from 100 to 250.that way all need is that then when decide what tunes best you can order a dozen  of that size. I believe BigJim sells them.
