I have been considering whether or not to sell off the bulk of my balling ball inventory. Some I will have trouble letting go of, such as the clear spare balls(I bid on a clear Hammer Gas Mask core just this week, but didn't win). And some of the Motiv stuff I will keep and eventually drill, but most of them I will never drill.
A lot of them I got for a really good price with fortunate timing, and a lot of them are also pretty much worthless.
For you guys who have a significant inventory, have you considered selling? By "significant" I mean more than 50 undrilled NIB balls, not the cute little collection of 10 or 20 already drill worthless items. No offense intended.
