I typically create a couple of trips or quads every now and then and invite a few friends ( them being 1500-2300 if that' an issue). Alwys looking for new partners, send me a PM when you have a slot open and I'll create and invite asap.
Btw, check out "1300+ RANDOM triples" thread here in callouts, looking for people willing to play trips with random partners against random opposition.
