I agree with the general sentiment already expressed. I was kind of in your shoes after my ASA 101 and 103 courses a couple of years ago. The course was taught on a C&C 29 foot boat with wheel steering, and it was just so intuitive, that I thought it would be preferable to tiller steering. Well, it was very difficult to find a small boat, say 25 or so feet with wheel steering I just gave up. Once I got used to the tiller, which took all of about an hour, I've not felt the need to go to a wheel.
