Got to be honest - Travis has been fairly slow as of late from all the reports I've seen. Unless you have a good graph on your boat and you know how to video game fish, you might not do very well. What day are you planning this trip?
The white/hybrids will eventually start moving up into the coves around Grelle / Muleshoe / Krause and that could make for a good day if you dont mind fishing minners. The weather and the flood event has really been adding the level of fuckery on the highland lakes right now. Even bank stomping my honey holes, I haven't landed a fish in my past three outings.
I'm hopeful the prespawn fishing on Travis will be really good this year as the water temps rise (possibly earlier than normal this year) If your trip isn't for a couple of weeks, I'd suggest the following lures:
- dragging a jig (boring as hell but will be productive around ledges, humps, dropoffs)
- paddle tail swimbaits on a weighted swimbait hook
- lipless cranks and jerkbaits
