Drew (and others) I chose "The world's fastest racetrack" because the back of the shirt will be seen by lots of folks that don't have any clue about Bonneville. If you're trying to help them begin to understand LSR - the generic reference to a racetrack will be understood pretty well by everyone.
I expect that there are lots of folks that don't know what a dyno is or does, so that one leaves them guessing. Hallowed ground is fine - but again, needs some context to be meaningful. The WGBS detector - well, again, it strikes me that a common reaction upon seeing it is "hunh?" What's that mean. Sure, it's a conversation opener, but if there's not a conversation -- the reader goes away with no clue but a generic WTF?
Speed is King is close to good, but again, it will take seeing both sides of the shirt to make the reference complete.
That's that. But since Nancy and I make t-shirts at our Kudos Design business -- might I ask what you're doing? If it's a small run of 'em - we might be at least competitive in price because we don't have a set-up charge nor artist's costs. We do the kind of printing called "dye sublimation" - which gives absolutely full color directly from a photo or your non-photo art (logo, text, etc).
Okay - ad is done. I probably will want a shirt, too. But what is going to be on the front?
