The folks at Fat Head's are very friendly to homebrewers. They've hosted and sponsored our club's annual competition [Society of Northeast Ohio Brewers (SNOB) - "Son of Brewzilla"] for the past five years. We'll be holding this year's competition at their production brewery / taproom tomorrow (11/7/15). I'm spoiled - my office is less than a mile from there. Head Hunter straight from the fermenter sample port is wonderful.
Wort H.O.G. - have you tried the Bistro Chalk Markers on your tap handles? They're pretty narrow, so you can fit more info - and they come in colors, too.
