I share the same philosophy as papa joe. I have a Plano box filled with various colors of tubes and 3" to 5" grubs, my personal choice is kalins because I feel they have the best action on a slow retrieve. I do also carry a few BPS and zoom grubs too.
For rigging I go with various weights of slider heads or a plain jighead with the grub if there aren't many weeds. With this box I feel I could hit any lake that has bass and I could catch them.
For the tubes I generally fish the hopping them off the bottom, but get a lot of strikes on the initial drop. The beauty of a tube is that fished on bottom it imitates a craw. Fish it with a stop and go retrieve up in the column or a big lift and drop it can imitate a swimming or dying baitfish. The tube is probably the most versatile bait out there.
For grubs I vary the retrieve a lot, even bouncing if off the bottom. The one thing I never seem to do is a straight in retrieve. All I can say is that grubs just catch fish. My PB Muskie and largemouth were caught on a grub. Grubs do pair well with swim jigs, but those can get pricey quick.
When fishing a new lake I look first for visual cover like reed beds, docks, weed lines especially those on a break, lay downs, etc. I would start working those areas first. If those don't produce, I would start working structure like points, ledges and sand flats. If I get to the point of fishing structure, I am in trouble because that is a weak spot in my game plan. I will say sand flats between reed beds can be money, don't just put the trolling motor on high and cast your way over to the next reed bed.
For cranks, I could get by with a few. I would carry a lipless bait or two, my current favorite is the red eye shad, but have done well with others like the rippin rap. For square bills I like the Bill Lewis echo and the Bandit 100. For deep divers I like the Norman deep little n and dd22, Rapala DT series and out of production cranking rap. The square bills and lipless work on shallow flats and I cast them in and around reeds. I have been known to go through the middle of a less dense reed bed and slowly work a squarebill through it, giving the fish they haven't seen in that cover. The deep divers cover the weedline and ledges. Lipless baits have worked at times for me on deep weed lines too
