I did the ebony star laminate upgrade on my dob this week and its amazing the difference it makes! I'm still using the stock teflon but now the scope moves soooo smooooth!
Where before I had to bump and nudge my scope to move small amounts I can now just apply a small amount of pressure and the scope movies very slowly and smoothly. NICE!
I also have a portion of laminate left over which I would be happy to sell and would be enough for most dobs. PM me if your interested.
