Troutly,
You are right it was a very sporting challenge but who was gonna be the mediator? Someone that is impartial to both sides of the coin. I guess money talks and BULL**** walks.
Mr. Threadstarter did not want to play.

How many people here have been told by a few SBI F-2 racers (within the last 12-18 months & don't mention names) that they needed to "bump up their engines" to even try and stay close to the "cheaters" in F-2? I know quite a few and no it is not "hear say." It came from the horses mouths.
I even know of a local 'L' class boat that got walked by one of the F-2 boats and this "L" class boat has 750hp a side!
