With regard to throttle using the exercise mats, 11bravo, I think that is a good option but if they were to slide at all(as you had concern), a little double sided carpet tape or adhesive backed velcro would probably stop any sliding issues. Also, if anyone would like to see my instructions for the stance platform and those in control of this site do not mind, I would be happy to post the instructions for all to see here -- as far as I know this is the best site going for information about golf simulators and I am happy to add anything I can.
