Well, Doom, I'm not sure what part of Chicagoland you're from, but I'm from Kankakee, and I'm going to try to put together a singles scratch league on Wednesday nights next year. The plan is to use PBA, WTBA, Kegel, etc. patterns, basically a different pattern each week and treat each week like its own individual tournament. If you're looking for a scratch environment on challenging patterns, maybe this will be for you. I'll keep you posted as details come together.
On a side note, you may also want to consider the tournaments put on at Town and Country Lanes in Joliet. I just bowled an 8-gamer yesterday on Kegel's Autobahn pattern. They run quality events, ones that reward the best bowlers! They have scratch and handicap divisions at most of their events, so you have options.
