I have been shooting and bare shafting ALOT lately trying to get my thunderstick all dialed in for turkey season.  I have a string from 10 ring on the bow now.  12 strand fury.  I am pulling around 49lbs at my draw which is maybe a hair less than 27".  I figured a 29" .500 with 200-225 would be close so I started there.  I had some arrows from previous set ups.  30.5 inchers were way weak.  I found that the bow likes 29" .500s with 175 up front however, I would like to shoot about 225 up front but I am always afraid to keep cutting.  I also hate knowing that it is possible to get a false weak even though I know the arrows are definitely weak at 29 with 225 up front.  I know that the bow and arrow set up varies shooter to shooter and bow to bow but is it common for a bow to require a stiffer than normal arrow with a high performance string?  And is it reasonable to rule out a false weak?

Im probably over thinking all of this.  I have just been shooting so much that I constantly am second guessing myself even though the proof is in the pudding.  I'm still learning and enjoy the help I receive here so thank you everyone.

Any time you change the string, you need to re-tune.  How much difference makes depends on a lot of variables.  Could be false weak.  I think when you go that heavy with points it screws around with the "rules".

If you really have to stay with that heavy a point, 1/4" shaft cut can make a difference and you have room to cut that and more. I definitely would cut no more than 1/4" at a time, and only on one shaft, as it's hard to put it back on.

I've been reading that a fast flight string can make you need roughly a 5# stiffer arrow?

Depends.  Lots of variables to consider.

it's not rocket science, but the simple machine of a stick bow has many variables that once understood, can be manipulated to improve performance.

Kevin, you have email

What kind of arrow material?  Carbon?  For me, carbon seems to recover quicker than aluminum or wood.  Pay attention to arrow flight.  Any wobble you see as it goes down range?  How about the wear on the strike plate?  I would say if you are getting straight flight and good normal wear on the strike plate, you're good to go.

Moved my nock up to 3/4 and wah lah great flight. Man sometimes it's funny how a 1/16 of an inch change makes all the difference in the world.

A little tuning and tinkering can go a long way...
