I believe stock design has the most affect. I hated the recoil from the Omega too. Along with the Renegade. Any stock with more drop at the rear of the comb than the front will be uncomfortable for me.
A stock that's lower in the front of the comb, or at least level won't bang you in the cheek and recoil straight back into the shoulder. Much more comfortable to me, and a better recoil pad will be more effective.
