I say just build your own and you'll be happy with it no matter what! No man can put as much time, energy, money, etc. into a boat they built and ever be unhappy with the finished product. Mine is similar to the Microdraft, but has quite a few differences. Floats in a true 4" and will scoot through 5 to 6 inches while on plane. It can be a little rough in a strong, close head chop, but its the driest flats boat I've ever been in.
Click the links in my signature down below and look through the different boats you can build. Take a close look at the OD18 (click this link http://www.bateau.com/proddetail.php...8#.Uhj1UT-IadU). I know a VERY experienced captain in Georgia that built one of these and he rigged it to the hilt. He fishes coastal marshes, skinny flats, and has even made a crossing from S. FL to the Bahama's. He loves it! I've fished with him in Boca Grande Pass and the nearby flats. I'll tell you right now that its a dry, fast, stable, and gas-sipping vessel. If you're looking for an all-around great boat that will do the most, I would highly recommend it. Heck, the guy will even build it for you if you'd like!
