rzredge,
Yes, I have shot both the Scorpyd and the Vision. I ended up with the vision because it felt more compact and balanced excellent due to the weight balance.
The Scorpyd is faster than the Vision and does it with less peak weight. This is due to the longer powerstroke and cams instead of a wheel. This makes the bow a bit longer and has a folding stock to make it easier to **** the bow.
Horton has been around a long time and has lots of dealers and is a proven company. I don't know how long RTD will warranty their products if the company went belly up.
For me Horton Vision is the better of the two.
