top 5 techniques

I'll assume you care primarily about #s of fish. Obviously, it would help to know if the lake is muddy/clear, deep/shallow, grass, no grass, etc. but, if I was going somewhere and didn't know anything about the lake/river, here's my list.
1. drop shot - it just catches fish anywhere any time of year
2. jig - super versatile: pitch it, flip it, swim it, etc.
3. chatterbait - I like the chatterbait better than a lipless crankbait or a spinnerbait, but these 3 are close to a tie for a reaction bait
4. fluke / floating worm - I like something natural or obnoxiously bright up in the water column that also comes through cover well
5. swimbait - When the above fail, I just throw a swimbait around anything that looks like bait on the electronics until it's time to go home

Profession Fishhead Justin Kimmel would probably say that anything other than Clemson orange and Roll Tide red should be ok, but Georgia Bulldog red is the least likely to scare them. Seriously, though, I don't know the answer, but most of my SPF sunshirts are light blue. I figure, it can't hurt to have sky color, and it doesn't absorb heat on hot days like dark colors do. I've been out on a 100 degree day in black and I thought it was going to melt to my skin. Gillz makes good shirts, I have never worm Huk or Aftco, but I hear good things. I always wear long sleeves because these SPF shirts are light and breathable so they are comfortable and convenient (because I hate remembering to put on sunscreen, and having it on my hands).
