Does anyone use multi-d sink tips with your skagit heads? I bought a guideline 4d scandi head, and the tips are about the same length and weight as a T-8/10 sink tip. They don't have the oomph to throw rabbit leeches, but they actually work pretty well with smaller/lighter flies on a skagit head. I like the H/I and 1/3 tips for fishing the top couple of feet and not hitting bottom in slower water, but I've also got a 3/5 tip that sinks really fast. When would a multi-d Sink tip that sinks at 6/7 ips at the end be better than just 10 feet of T-11?
