I have a T-top on my 23, I love it. I have a rocket launcher up there, along with my riggers, some lights, and assortment of antennas. I can fish 360 degrees with nothing in the way of the action. Prior to the 23, I ran a 19' maycraft and I put a Bimini T top on it. This was a low cost way to get a little shade and still leave it removable so I could get under the bridges or cruise without the top. The top was pretty nice when running. I had a pair of small outriggers that were attached to it (an option on the top) along with a couple of rod holders that I would only put light spinning tackle in. For the small boat and my desire to go under a couple of low bridges in the flats it was the perfect solution.
The only issue I had with it was that you MUST roll up the canvas before trailering. The extra wind load from the tow vehicle would have torn it apart (I never tried it but I was told this up front). Never had any issues while running the boat though.
Here is a web site you can look at with some more information.
