I think you'll love mos SiliSleev2 plus they are guaranteedHi DLD, yeah I can’t mind where I got these from TBH as I’ve had them quite a while from when I was last doing P.E maybe eBayer or that.. but it makes a hell of a difference..I’ve also got the few I bought off yourself a few weeks back but I haven’t tryed them with PF as yet as I’m still messing around with it to see what works best…I’ll try the other sleeves and give you a update..
