Nice to hear your response.The sled in question TRDon posted about was mine. It was on dollies at the time we were trying to figure this out.
We took it off the dollies and no problems whatsoever. Just wanted to share that info for those that were wondering/arguing. Thanks for all the input guys!
I'm a big fan of the KISS principle.
It does not take much under the rear of the skid to produce the effect.
You can all try some experimenting in the down time this summer. Use a totally flat floor to start and keep adding a little height under the rear of the skid. You will be surprised.
