Recommendation? 4Max Thumb discs

[Shorttime]

Recently picked up a 4Max Scout. My inner twelve-year-old is quite pleased with the purchase, but my inner INTJ can't resist wondering about some optimizing.

Thumb discs would be an easy improvement to one of the few (IMO) "weak" points of this knife.

If anybody knows where I can find some, I figure Bladeforums is the place to ask?

Thanks in advance!
