I have a MOAB that is 55# at 27". My draw length is 27". I currently shoot GT Trads 5575 at 30" with 175 up front. They fly great and the spine calculator shows a good fit. They end up being about 8.8 GPP.

I would like to move up to about 10 Gpp. I am considering buying GT Trad classics 340's which are stiff but they weigh more. I would adjust the arrow length to 30.5" and put 200 up front. The spine calculator shows good numbers. The GPP is 10.9.

Just curious what your thoughts are before I spring for the heavier shots.

Personally, I would experiment with putting weight in the shaft itself. By putting the weight inside the shaft (with weed-eater line or string, etc) you should be able to bring up the total weight without affecting the spine/tune very much, if at all. At the very least, it would be much less expensive to try than starting fresh with setting up a completely new arrow. Note: When you put whatever material inside of the shaft, make sure that it doesn't slide around freely. The inconsistent weight distribution could effect flight. Hope this helps.

have you tried heavier point? 225 grn fp

the more I learn about carbons the more weight I add to the front

just did some advanced testing on my BW speed-KE-momentum-penetration-efoc- arrow flight-arrow drop

the best overall I ended up with is an 8.4 grn per inch bowhunter ics 225-250 grn head ended up with 10.5 grn per pound bow weight 190fps was the most accurate at any distance out to 60yds

Fattony77...I would try the weight inside the shaft if I had enough arrows. But, I need to purchase some more because I have a tendency to lose them while stumping. Since I have to buy more I was looking at changing the spine to get a heavier arrow.

HOrnHunter...If I add weight to the front of my current shafts the spine becomes to weak. I tried to move up to 200g field points and my arrow flight was affected.

Thanks for both of your inputs.

ok sounds reasonable, tried cutting your arrows off some you draw 27" your arrows are 30"?

I will admit carbons are a different animal, been shooting them 10 years now and still learning

my problem is I grew up with woods, fiberglass and aluminum, throw all that out the window dealing with carbons, the high EFOC is a game changer I make my arrows to hunt elk, everything else they blow right through, there is a fine line when you start losing performance because of arrow weight,also makes a difference if your ground hunting or treestanding, I mostly ground hunt so I prefer a flat flying arrow, efoc has helped me with that

If you're buying new ones anyway, I'd look into the GoldTip Heavy Hunters. You should be able to stay in your comfort zone as far as spine & point weight, and just the shaft itself will weigh more. Maybe that will get ya where you're trying to go with them? Might be worth trying a half-dozen at first, anyway. Let us know how it goes for ya!
