Seems a bit odd... the standard SF Pro is quoted as 11.5 oz. The difference between the weight of the T18/15 frame set of the standard and the T15/12 of the UL should be more than 0.4 oz (11 grams). Maybe not much, but I would think around 0.6 oz, so I'm surprised FW don't quote 10. something.
I think there must be some confussion about the UL frame. The LE's are DT-10's not DT-12's.
The LS are DT-12's
