RE: Looking for something Faster!
Any of the three options would work well and exceed 150 mph.
I had a Mad Dog and really liked how it flew and the fiberglass fuse and pre-installed firewall made it go together quick. If you've never built a V-tail, that can be a little tricky, but not any harder than installing a firewall straight and perfect in a Zoomer or Napier.
All good airplanes. Pick the one you like, but I think the MadDog will be the most user friendly in terms of getting use to speed and landing these sleek airplanes. You may find landing the hardest part.
