I've been told numerous times that reds don't readily hit topwater plugs. That's simply not true. They'll pounce on a topwater plug just like a largemouth bass will. The bone colored option is very good. What I've seen some anglers do is paint a bright orange splotch just under the head of the lure for more flash as the plug is snaking through the water.
Fingernail polish is good, since it dries quickly.
What you're going to find on Pringle is lots of floating aquatic vegetation, especially during summer months. This can play havoc on treble hooks. But with a little bit of accuracy you can pretty much fish most lures without hanging up too often. What can be aggregating is when fish burrow into the grass after being hooked. Thats when you'll lose a few good fish.
