Sorry for the delay. I had HS graduation for my daughter today. I have approximately 250 of the 175s from the initial bulk purchase. I'd trade you 1 to 1 for the 120 BTs. How many would you like? Just a handful for testing, or more? I'd take just about as many of the 120s you're willing to part with.
Also, if it's easier, my cell#: 208-241-2045. Call, text.
