At this time not a lot of information to give out on the 2007 Hoyt bows, other than several new models, two new cams and a new XT3500 limb.
Several models feature what Hoyt have called 'StealthShot' which is a similar sytem to the STS string stoppers. You can see them pictured here, they look like lower cable guards, basically they act in the same way as Mathews string suppressors, taking the vibration out of the string.
November 1st is the official launch date and we should have pricing etc around that time.
This is info I found on another site.
I have the Vectrix on order myself.
