I have a Goodwin set-up, Although I have not tested it myself head to head with another sled. Greg Goodwin did all the testing and development on my sled and one other F7, supposedly for the F7 kits. I do have STALKER ATS data that I have posted before. I can tell you this, according to Goodwin they tested my sled and a clutched (dialed REV 800 X) and the F7 sp clutched and the REV 800 X clutched on snow ran pretty equal. Whom ever got the hole shot one the race. The race was 1000 feet.
