Silvertrout, Im not sure about a 2-hander for trout but if speycasting is what your after that single hander will do just fine. Anchor casts are simple & great fun with a single hander.
There are lines that cast beautifully with a single hander (airflows' 40+, rios' outbound etc) Snake roll, Perry poke, double & single spey, snap & circle T's. You will NEVER overhead again on rivers. ;D
One big advantage to speycasting with the 'little rod' is how you can control the wind & let it work to your advantage. Upstream wind...anchor over your upstream shoulder. Downstream wind...anchor below your downstream shoulder. This will inflate your d-loop & send your line incredible distances, with a simple flick of the wrist :beerchug: no false casting, no tangles behind ya, just roll & fire away.
Good luck & tight loops!
