Thanks for the information! I was at Hahn AB, and the Schwenkbraten I'm familiar with was whatever we got in that area, ranging up and down the Mosel River at all of the wine fests held throughout the Summer and annually at the Pig Fest in Wittlich.
This was 20 years ago, and I remember they were pretty thick, but I wouldn't say more than about 1" tops. I'd remember 2" thick slabs on a brotchen.
I'll also look into the schwenkgrill.
