I do one hand my 192t pretty regularly, they're made for that when climbing. Keep your body out of the plane of the chain, know where the bar tip is, & don't use real aggressive chain. Oh, & adjust the brake real light so it'll trip on inertia only. Nice buy on that J-Red!
AC...are you coming to the get together? I'd like to bring my 192 and see how to adjust the chain brake.
