I pulled the trigger and purchased the i-s12 Mirage this weekend
. Couldn't demo on the water (banged up my knee) but unpacked, tried all the widgets on it and stood on it etc. I really liked it a lot. For $1250 (2012 model used a couple of times) i thought it was a good investment. Thanks again to all on this website that I will continue to look to for advice. And hopefully provide some contribution.
I see what you're talking about GasYakker, about the wheels and where they are situated. Plugged in the hobie wheels while there. Because of the weight issue (on the back-, crate, tackle, anchor etc) i did not purchase the hobie wheels. I will get the balloon wheels that can be strapped on wherever it makes sense on the inflatable.
