i have a 55# martin x200 recurve that i have been shooting wood out of and am wanting to try some carbons. i draw 28. i have a dozen 5575 gold tips full lenght. flcthing is with three 4" feathers and wanting to use some where around a 150 grains up front.(i am willing to go heaiver if need be) is this possiable. i will bare shaft tune the arrows. what will be a good length to start with.  thanks for any advice.  :D

I would try them full length first, once you cut them than you cant put it back on. and try different grain field tips

I would head on over to O.L.Adcock webpage and read up on his tuning section he has and after a read through, then head to the bale for some shooting, the arrow point test kit that can be purchased with the 5 different weights helps a lot when trying to get a new shaft/point combo, but full length is the best way to start

I did what you are about to do based on advice from the prior owner of Sipsey River (THANKS!)  However, I failed to calculate the desired arrow weight first.  I want to shoot 9 - 10 grains per pound and it seems the easiest way to add weight is with point or insert weight.  I now have well tuned arrows that fly very well, but are only 8.8 gr/lb.  If I had it to do all over again, I would first calculate the final arrow weight needed for 10 gr/lb, then adjust the shaft choice, arrow length and tip weight to achieve something close to that weight.
