Here's a picture taken a couple of years ago at a float fly in Michigan with the designer, Laddie Mikulasko. The plane on the far left (silver) had retracts on it but the owner has removed them since he felt the weight wasn't worth it. It did look cool taxiing to and from the water though.

I'm also attaching a list of modifications that I sent to a friend that was in the process of building one a couple of years ago, based on my experiences with the four I have built. The other pictures are referred to in the list.
