I would highly recommend the Abu 6500CS Sports Mag.
I purchased 2 of them last year and found them to be as close to backlash proof as any conventional I've thrown.
Dial up the mag to start, then back it off as you feel more comfortable.
Last year they were only available overseas. This year Mikecc has them at a much better price than I paid.

Good luck,
