BB, take a good look at the left side cables on that Bullet. Most guys would have trouble shooting it without the cables clipping their arm. I say most guys because most are shooting too long a draw length and even the string slaps their arm. The cables are about an inch to the left of the string so you can imagine what problems are encountered.

That's not to say it's not a good system. I think it's one of the best cabling systems going as it does eliminate all torque in the bow itself. Pretty much everything, the rest, string and sight are right in the middle of the bow. All cam lean is eliminated also, something that isn't so for most solo-cam bows. Efficiency goes up due to less friction.

Yes, there is a little more vibration, but that is because the cables are not attached to anything that dampens them. I might have to try some Leeches or something on them and see what happens.

It's just more important to get the drawlength correct. I have two Martin bows with the X system and those cables just barely touch my arm sometimes, but I still don't need an armguard.And I don't shoot a bent elbow either. It's all in drawlength and proper grip (no-grip).
