Mix the two up! Bring a rod rigged with the wets and the other with the nymphs.
Start off looking for active fish and whack them with the wets. When you get those fish go to the ones you can get with the weighted nymphs. If you see another active trout go to the rod with the wets and catch it, then go back to fishing nymphs. I have been doing this on certain streams while practicing and the catches are impressive and they are on really short stretches of water.
so you can do both!
