I was talking about the un=modified superspeed rail and modified subrail with superspeeds k66= BAD
I thought I had the perfect opportunity to document and video the difference between the two back when my table was first restored. The contract I signed said the restorer of my table would install K-55 Black Diamond cushions, no mention of rail mods, and I knew I would be getting custom pro-cut rails from Mark Gregory...so anyway, I was setup to document the two setups, but low and behold, guess what the restorer installed on my rails? Yes, el cheapo K-66 cushions. Just like what Geoff mentioned earlier, the nose cushion height was 1-1/2". It played terrible, there were many situations that weren't even possible, for example a 5 rail bank/kick, or even a two rail back and forth, the second rail contact was a crazy angle. Oh well, maybe this post will give a heads up to anyone who runs into this situation again to document the difference. Needless to say I was ecstatic to get the Mark Gregory rails installed, it was like real pool again. LOL
I want to put a good plug in for Jack Zimmerman as well. I sent him the original rails for overhaul and those original rails now also play lights out. In the case of those rails it was pretty much a no-brainer that they needed new sub rails, they were stapled out and the rail facings angles were all over the place. It was obvious that my table had plenty of history at the old pool hall in Waxahachie Texas and it was time for overhaul.
