Vortek Moly Piston Seal or OEM Piston Seal?

About 25,000 shot ago I installed a Vortek kit with a Vortek Piston seal in my TX200. Since then, I have reinstalled my OEM mainspring with a Tinbum kit, but I kept the Vortek Moly seal on the piston. The last time I had the TX200 apart to install the Tinbum kit (About 5,000 shot ago), the Moly Seal looked good.
My TX200 is quite accurate, and shoots JSB 10.3gr pellets at 799 fps with a 7 fps extreme spread. Someone at my air gun club told me that a OEM piston seal could improve my velocity a bit.
Has anyone ever compared the performance of the OEM piston seal against the Vortek Moly piston seal in their TX200 or Prosport? Thank you!

I've not compared the moly seal with a stock seal in my TX 200. I can tell you if the seal is too tight it will reduce your velocity. Conversely if a seal is looser the velocity will increase. It's kind of a balancing act because if a seal is too loose the piston will slam harder into the end of the compression tube which can result in a less manageable shot cycle.

I saw about a 20fps increase with the vortek seal in my HC and MK3, both in .22 over the stock seal.
