Frank, The Wheely has either 80% or 65% mods. Whichever one prefers. The advertised speeds are tested at 80%.

In the owners manuals, BowTech rates their bows at 70 lbs. (unless that particular model doesn' t come in 70 lbs). When a 60 lb. model is built and tested it' s rated 4-6 fps. slower than the 70 lb. and a 50 lb. model is rated 7-10 fps. slower.

These tests are done using a 5 grain per pound arrow.

Corb, If draw force isn' t a factor, I' d look at the Extreme VFT. It can be set at 80% let off or less if so desired.
