I went 7000 miles on my speed and no tail/bottom problems at ALL!!! From Southern OR to portland,ID, WY,SD,WY,CO,KS,OK,AR,MO,OK fabed and mounted A rear hitch and towed a trailer back, TX, NM, AZ, CA,OR. no problems or power issues entire way!
AND back alive!!!

I would choose a speedy just because of the brakes. I would also up grade the way it breathes & front springs and you'll be very happy boy!
