Throw in another vote for the Havoctec (like everybody didn't see that one coming). I have tried and/or owned two out of those three bows and I would rate the Havoctec as quieter and more well put together than the other two...(though I wouldn't mind shooting any of them for the upcoming season..<img src=icon_smile_wink.gif border=0 align=middle>) Plus, you have super adjustable Versacam to play with.
Try them all out and see which one you like to shoot the most...that will be the true test.
