Have you tried the new "dragonfly" fins for fluttering?

Just kidding! This is a composite showing how the fins operate under the boat when "fluttering". As you can see, you can get pretty shallow and still operate -- about down to 8" with the Revo and 10" in the Outback if you're careful. You'll also notice the 2" additional length of the Turbofins are inconsequential as to how shallow you can go. The old wife's tale about Turbos not being able to go shallow was apparently dreamed up by someone who doesn't know much about the Drive and how it functions.
The ST are nothing to sneeze at though. They are almost as easy as the standard fins to operate and run almost as fast as the Turbos; they cost less and are simpler to install -- can be swapped back and forth with standard fins with no mast change (for oyster bars for example where extreme abrasion resistance is desirable).
This brings out one of the great attributes of the large rudder. The slower the speed, the greater the difference. The large rudder gives directional control
almost down to 0 MPH -- a great asset when fluttering or holding position in a current, tide or crosswind while fishing -- even while drifting. This applies to all the Hobie kayaks. Under normal operations (non sailing), both the Revo and Outback get by OK with the standard rudder (IMO). For me though, the first upgrade on all my Hobies is the large rudder. It gives maximum authority in all situations, any emergencies, and is much more hands free (less re-trimming). Can't beat it for the price! Too long in skinny water? Likely not, but if so, just lop off the bottom inch or two and it will do the same great job!
Some excellent points have been brought out about both the Outback and Revo. What works best for you probably depends on 1) how much gear do you like sitting around. The Outback trays are hard to beat in that regard. 2) What kind of water do you fish in? The Revo is faster, quieter, handles wind, chop and large wakes better. This makes it a better choice in active water like the ocean or when maximizing range is important.
The boats feel and handle quite differently and each excels in its preferred environment. Yet, both are competent in large variety of circumstances. That makes it almost impossible to make a bad choice. Whatever you end up with I think you'll be very pleased!
