I think you've made a good choice, based on my experience with the LFM-1 and the SMS-1. Outlaw's guide for the SMS-1 is a
great resource for somebody looking at the SMS-1 (and to some degree any sub EQ system, including R-DES). If you haven't done so already, download
the PDF and read through it - it'll be a big help when you start setting things up.
