Man dude, you would be talking more the 30 fps I believe....Prolly more like 50.......I'm no engineer though......

I would think you have to build it with some sort of shoot through system, I feel like if you used a roller cable gaurd you might be putting an awefull lot of torque on the system.....

Wouldn't be the most forgiving bow in the world, but it just may be the fastest...
