Thanks heaps for taking the time an making a detail reply - appreciate it and I'll see how I go on Friday.
No problem. I also saw you dont have the RSD pistons for this week. AE#2 are close, so use those till you can switch out.
Try paragon on your sorex's for 30 min, then wipe them off or take a few laps slow to get it off your tires. If your racing at night 28's are usually the ticket. If the surface is rough, monitor your tire wear. Sorex's last, I would bet with 21.5 you can get at least 10 races out of them before they start to fade...
Good luck.
