We mend to prevent tension on the dry fly or the indicator. All flies could drift drag free in the current if not for tension from the attached leader. So it’s our job to eliminate or at least limit that tension on the tippet and to the fly.
This Hop Mend is an arch. It’s a steep and quick half-oval. It’s a fast motion up, over and down with the fly rod. It’s powerful and swift, but not overdone . . .
