Since I'm not a dealer Kirt, I can say what I like.... and I know it completely subjective but I think the stealth looks awful... like a toy, plastic. production kind of boat, not a racer. I know that is not contructive, and that I'm biased as I own a T4.9, but it is ugly!!!
As for the rudders... another benefit would be that induced drag from tip vortices would be reduced/ cut out altogether. Fairly minor, I know, but it may overcome the extra surface drag?
