Thanks, GG. I'm not quite as poor a caster as I might have led on, but the thing I don't do consistently well is incorporating that slight upstream mend that allows the fly to lead the line through the swing into my casts while airborne. That's why I was thinking an intermediate head might be difficult for me to fish. The best casters I know can make the line land in just about any shape they like to maximize the effectiveness of their swings, which can be a tremendous advantage when fishing lies across varying currents. I'm sure I'll get better with more practice.

Thanks for the detailed info on the intermediate offerings. Good stuff.
