ESS Tuning Twin Screw Superchargers Discontinued?

It has been a couple of years, and I figured I should write an update. The drive belt is a little chewed up, nothing major, but I saw it while doing my valve cover gasket. The one that came with my kit is Contitech 6PK1900. I think I will go to 6PK1905 since I am running the alternator overrun pulley, which has about 19mm more circumference. The belt does not go fully wrap around it, so another 5mm is possibly appropriate. I suspect the belt is chewed up because I used a Febi tensioner. I am not so sure about Febi for this part, 11287838797. I am going for an INA unit. An alternate belt part number is 1060750 where the 750 stands for 75 inches, or 1905mm. 1060747 is the next closest thing at 74.7" which is 1897.4 mm, but that is even smaller, so not ideal. Let's see how this goes. Meanwhile, the ESS TS2 is still going strong. I have the 8PSI kit with an 85mm pulley. I see ESS includes EPK1900 for the 81mm TS2+ pulley, giving me more reason to think 1905, or possibly larger will be OK.
