I just purchased an old bear grizzly from my local archery shop for what I think is a great price, 100$ !!! anyhow took it home and played with it a bit and it seems to like a 7 3/4" brace height, any other recommendation? I did not have a lot of time to shoot but it really quieted down when I twisted it up to that. Also the bow is 45 @ 28 and I wanted to see if anybody had suggestions as to arrow choice? carbon preferably, I make a mess out of aluminum in short order. My arrows are sorted out for my 53 lb longbow and I think they are a little stiff on spine, any help would be great, the bow has the usual amo markings but is numbered kr41421 above those. any ideas as to year? It appears to be maybe rosewood with a maple strip? just guessing, but really in overall good shape and I shot some really nice groups even with poorly matched arrows so very interested in getting it set up right, The custom longbow may stay home this year on opening day!
