RE: No peep on FX
Roseaukaine,
I have an FX 29" draw and 70 lbs limbs. I shoot with a no peep mounted under a SME hybrid sight. It works great. I am sure you have noticed the very small sight window on the FX. I just mounted the No-peep so that it was below my sights. It works great. I originally bought the No-peep for low light conditions. I was not able to see my pins as it approached the end of legal shooting hours. Served that purpose well but also had another advantage. I was able to see immediately if I was torqueing the bow.
I did help out with my form. Just a way to check hand torque on the bow really. The low light visiblity was still the main benefit for me.
