I currently am shooting an Xi impulse I have had for about 10 yrs, it has worked great and I can shoot it well, so change has been slow to come. However, I know I' m behind times for todays techno, and I could probaly shoot better with a new bow, I have looked at the mattews, and bowtech lines..... they both look great, any suggestions or comments on certain models or other name brands I should try before I buy?? thanks....
