Francis,

Watch out for those limb bolts. It looks like they are getting towards their limit.
I don't know that bow (but similar to my old bow). If there is too little thread you run the risk of it
stripping and doing some damage at draw.

Let us know if the Sims helped.

my best advise would be to get a sims scoil. i just got one and i could feel the diference right away, and they only go around for about $20.
