Technologies I look for in my bows:
I'm a binary/dual/twin cam shooter, so I'm only interested in buying twin cam bows (Mathews Monster, Bowtech, etc).
Then I want a hard/aggressive cam, meaning I can get a lot of speed out of a my short 28.5" drawlength. I also want heavy limbs.
I like a short axle to axle for portability.
I shoot well enough that brace height doesn't matter to me, but a lot of guys want a longer brace for forgiveness in shooting form.
How quiet a bow is doesn't matter to me in terms of jumping the string, but loud sounds are wasted energy. I want an efficient bow, which means it must be quiet. Quiet bows, by nature, also tend to have a smoother, more polished draw (feel) to them, which means a lot in shooter comfort and efficiency. It also gets old shooting a loud bow indoors.
