Well, meanwhile my eyes are far from being great but I have had only very little complaints about significant tint shift in the recent models with SMO reflectors (SF47T, SD01, SC31 Pro). I remember their first models with XP-L2 and SMO reflectors had horrible tintshift, e.g. SP32. As always, it's hard to please everyone's favor. If they chose to using OP reflectors from now on, some people would start ranting about wasting throw/candelas. If you check the SP70 BLF edition thread, you see lots of discussions and opinions about SMO- and (soft-textured) OP-reflectors. ;-)
