Mine is slipping too so I'm saving for a Helix clutch. Awesome GTI seem to be the cheapest
Sachs is another option but a few guys on here have had problems which was enough to put me off
As long as your not getting any rumbles from your flywheel it should be fine.
You could go with an OEM replacement clutch (cheapest option) but it may just start slipping again in 12 months time
