I think it is too much line. It would be good for turning over large dries only in the hands of a weak caster. It will help a weak caster in this way, but with a proper powerful cast it will turn the fly over with so much force that there will be a snapback before it hits the water. I have tried and the only way to fish dries with it is by modifying your cast. It is also not so plesant to do. Maybe at greater distances it would be ok for this but not from a boat.
