Thanks for that link! Bookmarked (until KD changes their website again!). Well I was thinking of an under-driven XM-L for runtime / general use light. Or even XP-G instead of XM-L. Way I see it, 700mA to an XM-L should give about 275 Lumens (according to the test chart here). Guess there aren't many 20mm driver boards out there. The P60 uses 17mm drivers, right?
