The ESP Guitar Company

hey guys. i'm new to the forum. i'm the proud owner of an M-I NTB (which is a beast of a guitar, and very fun to play). i've had it for about 5 months i think. i play it through a loaded boogie mark iii combo (blue stripe, if anyone cares about that sort of thing). enough about me... I was wondering if anyone knew the radii of the 4 different m-series guitars that were offered in the states. i remember seeing a chart floating around for the japanese catalogue of esp's (all standard and signature series models). i know that the m-series models are different for the japanese and usa markets tho. i'm planning on trying to lower my action at some point, and i'm not sure what would be a good height because i dont know my radius. also, i think i might get one of those bolt-on m-ii's at some point, and it would be good to know ;). thanks in advance.
