Archae, trust the forum on the rudder. Your dealer obviously doesn't have much experience with this accessory. For $23, it's by far the single best investment you can make. It will turn your Revo from a "family sedan" to a "sports car". Huge difference, with rudder authority down to 0 speed, much better control in the surf and substantially less rudder adjustment necessary in swell, chop and wind.
Turbofins work as well as standard fins in skinny waters. With one foot forward, you just flutter the fins against the hull. In this first picture, you can see the feet are operating the pedals (with Turbofins) in this shallow inlet:
Here, with Turbofins still in, I'm running in just a few inches of water with no damage or contact (Hobie Adventure). The Revo has a little more draft but not much:
It just takes a little practice!
One caveat -- While the Turbos can produce more acceleration and speed, they are not as durable as the standard fins -- they can tear and scuff under the right circumstances. Fortunately in two years I haven't broken any yet. Nevertheless, I couldn't imagine not having them (and keep a spare set just in case!).
