The 2 are not even close in their surface texture.

Hey John, thanks for your advice and knowledge on this subject. One question though if I may? Seeing as the 50 finish ebony star has been discontinued and as you said some people still have it but would not part with it any time soon, what exactly do the professional custom telescope makers use then? What happens when all of the spare stuff laying around runs out?

I would try cutting "leads" on all of your plastic pads to help reduce "sticktion". In other words you should bevel the 4 top edges of each pad at 45 degrees.

I actually did do this to all three pads already after reading a similar thread either on here or cloudy nights. As you said though replacing them with teflon is the ultimate end goal but for now this has been a massive improvement over the stock setup.
As for the plastic, I didn't pay for it. It was an offcut they had spare.
Thanks again guys. Appreciate the help!
