Ky,
I see you are still torn between the HavocTec and CyberTec! HAHA!! I know it's a hard decision. Heres my input:
Most people will say brace height. However, I cannot honestly say which one has the greatest affect on me. The reason I say this is because I shoot my HavocTec with the 31 1/2" ATA and 7 1/2" brace, just as good as I do my Vortec. The Vortec has the same ATA and brace height as this years CyberTec. I don't have a level on any of my sights either. I will say that I have noticed the Vortec was slightly, (and I stress slighty) easier to shoot, because it had a greater mass weight. I cured this problem by putting a slightly heavier stabilizer on my HavocTec. It solved the problem totally. I shoot a Enhancer 2000 on the Vortec, and a 7.5" Vibracheck Isolator on the HavocTec.
To sum this up, I think that if you are a pretty decent shot, then go with the bow that you really want. In other words, I think you will shoot them both about the same, if you have decent form. This is just my experience, and I'm no pro, but I have shot for years, and I've basically shot both bows. Last years Vortec had the same brace and axle to axle as the CyberTec. Good luck on your decision. I will be waiting to see what you decide!
