I'm starting to think I'll keep the windsheild. I'm 90% of the time standing up while underway and usually hold to the top of the windsheild to steady myself with one hand. I don't like the idea of the esignglass enclosure, and I know the first bucket of spray that hits the wifey in the face will get me "that look", LOL!
Hey Brad, just out of curiosity, what's all that extra topside steel going to do to the handling of the boat? Is it going to effect anything? 
I'm trying to decide between a canvas top "half tower" or a hardtop. A hardtop can have a light weight non cored top or a much heavier cored top. The advantage of a cored top is mounting lights, antennaes, etc. is easier. I'm leaning towards a canvas top to save on weight and cost and planning on having an antennae mounting rail on top. I'd also like to mount my nav lights on the top so that will have to be considered. I'm told that a canvas top with aluminum structure shouldn't weigh more than 100-150 lbs.
