I initially switched to a MZE because I thought that my accuracy would improve for a number of reasons (no fletching contact, reduced effect of hand torque, etc.) and after switching I was able to add more helical to my carbons to aid in the broadhead tuning dept.

My right/left misses have disappeared! Whether they were due to hand torque or fletching contact with the rest I'm not sure (probably both) but I couldn't be happier with my drop away!! FP's and BH's fly the same. What a deal! HotLZ you're right, the draw is absolutely silent.
