i bought some berkley frogs the other day and rigged them weightless texas rig. my problem is that they spin or turn upside-down on retrieval and i cant get a natural presentation. what am i doing wrong?

Well In all honesty your not doing anything wrong, it is the nature of the bait to do so. Try a weighted holding hook like you would use on a fluke. You know it has the little peice that comes out of the eye of the hook that has all those barbs. It is weighted on the bottom. I think they make them in like a weighted wide gap hook form. Oh and to eliminate the line twist try a ball barrel interlocking swivel. They are rated got weight like test line. I think this will solve your problem.

Good Luck,

Peter
