Well I shot the Y25(12 shots)with the Excal stringand it was noisier then I thought it would be then I put on one of my Boo strings and shot another 12 arrows andit helped alot,had to laugh at myself because when I shoulderd it I tried to put my thumb thru the stock(too used to my other bow)opps.I am very happy withthe way it shoots but beleave meI will be putting a STS sytem on it,cant wait till the weather clears up so I can really site it in.....I also liked how it felt shoulderd and the trigger was fine for me.
