BSL chart? Larger Dynafit-compatible boot BSLs?

Are there any repositories of BSL charts for the various Dynafit compatible AT boots on the market?

I've recently come into the possession of a new pair of skis I'd like to be able to use well into the future (Thanks G3! Y'all rock!). There's a chance that I'll be changing boots away from the TLT4, if I decide that stiffer boots are in my future. If that happens, I'll still want my skis mounted close to boot center, preferably without remounting my Dynafits. So, before I choose where to drill, I'm hunting for BSLs of boots in the mondo 29-31 range (dynafits, megarides, Scarpas, etc.). Any help you can provide would be awesome!

I can't wait to try skis that are 2.1 cm wider than my 84 mm standbys... just standing on them feels cool.
