I showed a friend of mine the difference in torque between his reflexed riser, 80% letoff bow and my deflex riser ProTec with 65% letoff. I showed him how far you could intentionally twist the riser out of plane with the string on his bow, at least 60 degrees from left to right, and how you really had to struggle to budge my bow. He was showing that trick to someone else in a shop one day and twisted the riser so far that he popped the string out of the tracks on the cams.

But that's just how easy it is to torque one of those heavily reflexed risers. High letoff just makes it easier.

ewolf, as far as I know, only Hoyt, Reflex and Merlin have a deflexed riser in their lineup. Martin went to a serious reflex in their Cougar and Sceptor bows, so I don't think they've got anything in deflex any more.

For those who need a visual:

Deflex riser. Pivot point of the grip is IN FRONT of the pivot point of the limb butts.


Reflex riser. Pivot point of the grip is BEHIND the pivot point of the limb butts.


You can see, with the reflex riser, you're pulling back on the string and cams while trying to push the handle and limb butts away from the string and keep everything aligned in the same plane. With the deflex riser, you're pulling the string, cams and limb butts straight back from the grip, so everything is automatically kept in alignment.
