3 1/2" X-rap and replaced the trebles with #2 Owner bait hooks. No science to it, they just looked right. The action was unaffected and the lure worked fine.
I got a chance to fish for about 20 minutes yesterday and the modified X-rap worked great. The north side of my spot was dead, so I went to the south side. Second cast got a close inspection and the fourth cast got a hit. The hook-up was perfect; through the lip and behind the bone. Here are some pics, sorry about the quality.

The fish.
I plan on hitting the canals and lakes in the area tomorrow. I'll post another report on the single hook experiment.
