What should be a relatively easy way to check which offset you have is to look at where the caliper bolts on to the bottom of your Ohlins fork, if it looks as if its been machined with a 5mm step its the 15mm offset discs you require, if the caliper mount is pretty much flush with the rest of the casting its the lesser 10mm offset disc required
