Been dabbling around with these heads lately. Want to get others experiences as well to learn how to best run them. I first used the iFlight last winter on a favorite local run of mine that has a very slow swing. I found the head to be far too much sink even in the 6-8' deep run, even when equipped with a full intermediate MOW tip. The heads get a massive amount of sink, far more than I thought. A few days ago, I busted out the Scandi Short Int. head and put the same Intermediate MOW tip on it. I fished a run that moves quite a bit quicker, and is about 6' deep. I really liked the way the head cut through the cross currents and didn't seem to "lift" when pulling through faster seams. What's others' experiences thus far?
