Frank ,
Just curious as to why you think the Vipertec is closer to the Mighty Mite?I think its almost as close as you can get with these 2.
Vipertec:
32" ATA
7.5" BH
3.75lbs
300fps IBO

Liberty:
33" ATA
7.5" BH
3.8lbs
300fps IBO (that was my Birth certificate)

I would think the X-Tec would be directly comparable to the 2004 Patriot Single cam?........both 35" and 7" brace heights.

The Mighty Mite I don't think will directly translate into any of the Hoyt's lie-up on paper........7 3/4" BH and 320 speed?
