it seems like everything takes about two years for people to really start accepting... i'm just thinking of the introduction of closed toe boots.
a few people were super stoked by closed toe when they first came out and others were completely against them and most had not tried them... mostly because not every company had one yet. about 2 years later, everyone has a closed toe option and it is much more widely accepted
same thing seems to be happinin' with flex.
..maybe i have said this before, but i just think it is kool how it all has/is played/playing out. 4 hole mounting will be next if i play my guesses right
