If that's what Big Cliff meant, that's not the way it came through to me. What he said about a tight loop is quite correct ... a tight loop will penetrate the wind ... but the issue is far more complex than whether or not you throw a tight loop.
Wind casting requires a different approach - overlining is not a part of that approach. The truth is underlining works far better as I've fully explained in my articles, if anyone cares to read them. Whether they do makes little difference to me.
Besides line selection, the rod and the casting stroke become very important. One thing I wil assure you: and 8-weight line will never beat a 6-weight line against the wind -- loops or no loops! One caveat: I assume we are discussing a 6-weight rod...
