I tried to bare shaft some GT 3555 last night and kept getting a nock left-- weak. I cut them down as much as possible and ran out of room. I have 100 gr inserts with 125 gr heads. I'm wondering if I have too much wt up front? I'm drawing about 26.5"-- about 45#.
Do I try a 50 gr insert?
Do I try the aluminum insert-- although that takes my FOC down?
Or, so I get some AD Trad lites given I have a Timberghost on the way at a similar draw wt?
Thx in advance.

Play with lighter point/insert weight to see if it corrects the nock left. How long are you arrows now?
I'm shooting GT 5575 29" with 100 gr insert, 175 gr head. 50# @28 and I draw 27. you might be weak spined, I didn't notice changing tip weight to make much difference. I think I could have shot anything from 125 to 200 and not seen a difference in spine. I just settled for 175 because of trajectory with my gaps, plus a good FOC.
Yes, your points are too heavy. Play with insert weights, then broadhead weight. I shoot bows in the 40-45# range and my draw is 28". I cut them @ 29", add some poly rope for weight, and another 225 up front. Shoot like darts.
The great thing about brass inserts is going from 50gr to 100gr or vise versa does not change spine of you arrow the 100gr insert is longer so it stiffens your arrow and does not change a thing so if 50gr works and you want to go heaver you can go to 100gr without any worries. Making a carbon shaft longer or shorter makes a lot bigger change to spine then adding weight to tip. I would try to make them work at least till you get your new bow then maybe make a change that may work in both bows. Widow
Sounds weak to me, Bronze. If it were me I would move up to 5575's and keep that FOC....but that's just me. The AD trad lites sound like a good idea as well. I believe them to be a superior arrow. Again, just my opinion. Good luck with it.

Just reread...sorry, I overlooked your 45# draw weight...hmmmm. I would still front load the 5575's. Probably end up close to full length. Just a guess.

wouldn't be suprised if your too stiff. try it, point load to the max and see if it gets better.
i now shoot 500 spine with 350gr upfront out of a 58# border recurve with the best flight i've had in years. struggled for ages with 400 spine but they were just too stiff.
yes i know that should be way too weak but it isn't! i'm convinced most people are shooting arrows that are too stiff now.
I dropped to a 100 gr point and increased my brace height 0.75". I shot thru paper and the windage was great. I raised my nocking point to accommodate for the nock low tear. Shot them outside and they're flying well.

I doubt very seriously it is an underspined problem.... or it shouldnt be. Is your release/form in check? I can get 35/55 to shoot pretty easily from my 55 pound bows with arrows about an inch longer and more upfront weight.
For the past 2+ years I have shot 7595 arrows out of my 53# bow and thought I was getting decent arrow flight. I'd try 5575 or 3555 spine and they flew like they were too weak. Well this year everything finally clicked from a form perspective and my correct arrows are 3555's. I have a 29" draw and cut my arrows to 30.5" with 200 grain points. I think all along my form wasn't good enough to get good arrow flight and I was mistaken that for weak spine. It also kept me from hunting with my recurve.
I'm not saying this is your issue but that is what my experience is. I'm obviously no expert so take it for what it's worth.

Agree.
Every time I read a post like this I think about how it would be so much easier if you would just switch to aluminum...I have some very nicely tuned carbon arrows but when tuning a new bow I start and often end with aluminum...having about 15 bows makes that kind of a necessity at times

Glad you got it sorted out Manolito!
I hope all is well up your way!
