When I want to use an indicator I use a brand called Float Master. They stay on the line, don't kink it and are fast and easy to adjust for depth.
Here's the link http://floatmasterco.net/
I've tried most of the others in the market and these are the only ones I've carried for the last ten or twelve years. They come in tons of sizes, shapes, and colors and are nearly impossible to lose. Easy to put on and take off but you don't have to worry about casting one and then watch it float down stream as they will not come off the leader, unless you take it off.
These are my favorite, others have theirs but if I'm going to fish an indicator it's going to be one of the Floatmasters!
