I currently use the gray felt sole and red/rust leather heel on my 3G Tour Ultras but find that I need a little more slide. Would the 'hard heel' option provide more slide than the red leather heel or is there a better option to get a little more slide length?

Thanks for the reply Don. I tried the orange cleat sole and teflon discs a couple of years ago. What I found was the cleat leather and the teflon discs were the same depth when attached to the shoe sole. The result for me was less slide than the gray felt solid sole because I was partially sliding on the orange leather. What I have decided to try later this week is just attach the teflon cleats without the cleat sole or I may take a used gray felt sole I have and attempt to cut out holes for the teflon cleats to fit into. I just recently developed arthritis in my left knee so any abrupt stops in my slide are something I would like to avoid...thanks again as your reply has given me reason to experiment a little with this....Hopefully I won't slide all the way into the pit!

You could try to find a shoe repair shop and have them attach some of the leather soles to some of the rubber heels that you don't use.
