go tmy attention pretty quick!! I like dark colors because I think it throws off a better hue/target for them to hone in on. I usually have 2 sizes and get an idea of what size to throw by watching the size of the flying fish. it always a good idea to have both the surface and subsurface covered. if they are finicky, they wont come up to the surface all the way. they will stay about 10 feet down and you will see them flashing thru the lights.
very rarely will you catch them in the bright sun on topwaters. it can happen, but is rare. I lucked out an popped an 80# last TFF trip in the bright noon sun! Both capts saw it eat my topwater!! it was one of the best feelings having the captains tell me I did a good job!
