Old Town is the best I've used.

I haven't really had a good shot with the WS drive, the one time I got to try one some idiot had broke the rudder control at a demo day. I did like the drive on the pescador pilot so I assume the WS drive will be like that but better.

I don't like the native, it has a weird catch to it during the cycle. When the pedals are parallel to the horizon they stick so as you pedal there's a hitch when either foot hits that spot.

The Hobie drive seems a lot more tiring to me.

I've heard the same about the Native...haven't had a chance to try them out for myself.
I've been thinking of Hobie Outback for awhile, especially since the new ones have a reverse....although it does seem like a complicated design that may not hold up too well.

Anyways, thanks for the input. Gave me something to think about.
