AS far as Where to place Strike indicators. If you are fishing nymphs on the bottom, place them so that you fly periodocally hits bottom. You will ose a few. If you make 4-5 drofts and don't bump anything they are too low on your line, move them. If you are getting hung up move the the other way a little.
1.5 times depth is a starting point. It depends on how fast the flow is and how heavy the nymph. Sometimes when it is fast i over weight them with two split shot and a shorter leader,it keeps them under better control. I find placing the shot above the fly 6-10 inches works for me. Some anglers like the shot trailing from the tag you leave after tying on the nymph. The theory is you sacrifice the shot not the nymph.
