Pete,
Since you're one of the "Swimbait Yoda's" (somebody else coined it) around here, what do you think about using slider type heads on swimbaits around grass, especillay for Hali's? I've tried it a few times with marginal success. I didn't put a ton of confidence in them and I had trouble finding a head that wouldn't "roll-out" to the side or swim sideways.
I finally found a package of 2 heads that seemed to do it right, on a trip to Oregon, but I tossed the packaging and then lost the heads. I didn't get any Hali's on them but the rockfish thought they were candy. Those heads were alot like the crappie/smallmouth sliders that Bobby Garland(I think?) used to produce, but they had more of a sharp keel to them do to having a deeper profile. They pulled through the weeds quite well with the line tie right at the front and could be rigged semi-Texposed style without getting much roll-out or rigged regular with out any roll-out. If you find any deep profiled sliderheads try them and let me know.

Tight lines,
Wade
