hi,i have an old pse thunderbolt and want to get a newer parralel limb one.shorter in a 30-32 inch range ,smooth shooting and of course fast for about 200.00 bucks.-----------------just kidding about that!!!seriously though im just a little confused about the whole "watch out with the double cam getting out of time thing"i was thinking about the martin cheeta or the like or the whitetail obsesion with the double cam.some bow techs got a few i like but the grips feel funny-like a square in my hands.but anyhow are these things that delicate they get out of time or is that just technical talk that i realy wont be able to tell a bit of difference in later.just was wanting some input before i drop some coin down.thanks very much
