Well I finally got a combination of arrow and point weight that works for me with the Buffalo.  Easton XX78 superslam 2315 30" bop with a 140gr field point. I have my brace set at 8 1/8 inches. This bow is super smooth and quiet at least to my standards. This is as close to a custom bow that I have ever shot .  I am impressed to say the least, tight groups and hitting very close to where I am looking. I split the nock and ferrule off of one of my new xx78 this morning I have never done that before. Made me feel kinda good when that happened then I remembered those things are like $7 each. many thanks to Stu Miller's Calculator, it saved me alot of time and money. Now all I need to do is practice, Turkey season is on it's way!!!   Still Haven't told the wife!

Steve,  I shot a 50# gamemasterII once, and really liked it.  Performed real well, felt it shot more like a 55# bow. I remember reading some comments about the gamemasterII afterwards that reflected my thoughts.  Like, buy 5#'s less than you want, it shoots heavier than it is, or it stacks some, go lighter on the poundage.  Is your buffalo pulling like a 55# bow to you.

BTW , No it definitly shoots heavy feels more like 60 than 55 I almost ordered a 60 glad I went with the 55.

Thats the way the Dorado's were too. Glad to know that if there happens to be a Buffalo in the future for me!
