Clutch friction plate question

Think I need a new set of friction plates as I'm still getting a bit of slip at high revs. Wherever I look the KTM plates seem to be priced per plate at about £12 - 13 each so the total rebuild is well over £140+

Has anyone tried the EBC plates like from here?...

If you can wait, I'll be testing them out this weekend when I do my slipper install...
If the pads are anything to go by then they should be mega awesome!

I just bit the bullet and purchased a whole clutch pack - you get the friction and metal plates, springs and bevel spring - its around the £220 mark.

How many miles on your clutch ?

Bike is now at just over 10,000 miles so I'm really doubtful that it's the plates. But half of these miles is with a Suter slipper clutch fitted which uses the stock plates. Still, I don't go around using the slipper that often as I like blipping the throttle too much and matching revs - old habits die very hard. I'm going to check what oil the last change was done with in case it's that.
