pick your poison with driftboats...clack makes a great flyfishing boat...alumaweld makes a great boat for pulling plugs and general use. i wouldn't run a fiberglass boat anywhere you run the risk of hitting rocks hard...fiberglass will break...aluminum will bend...aluminum's a lot noisier than glass, but a lot lighter....
i have a lavro...love it, but would much rather have a different boat...with more storage and more options. mine's pert near a bare boat with seats...no frills, but it works and we've done 2 day trips out of it on the yak.
