I like to see companies willing to got the WW rounte, so I applaud what they are doing. I imagine most of us (here on WW), wish most companies would push the boundies like this.
I am not a big fan of marketing.
The EVO NANO, very well, may be 40gm lighter because:
-they are using hardly any paint (less the the first EVO sl)
-perhaps different (lighter) paint
(like with the BH superlight and how they had Parlee help them do a super-light paint job)
I could be wrong, but when a company goes from there (great frames) like the HI-Mod and drop like 250-300gm and intro the Evo SL
........then a year, or so later, they say they have an NANO as if they redisigned a, relatively, new frame (by only 40 gms....claimed )
.....odds are it's marketing (as if they "redisigned the layup" or some "magic resin reducing technology" or something)(but, 40gm is 40gm too
....claimed.....even if it is paint
I could be wrong, but I would bet, heavily, that the reduction of 40gm does NOT come from a difference in the frame of the Evo SL to the Evo NANO (I would bet it is a diference in paint)
I guess I am cynical
(P.S. this is not intended to sound intense
