Super pumped
Couldn't believe my eyes when I saw this coming soon. Knew I needed to have it. Can't thank Don enough for putting out such a high quality BCG with such low quality humor.

Great BCG
This is my new favorite BCG. It has all the features and QC you want, and a Dickbutt added for good measure. It’s fantastic.
