BA & ETM -
to be fair, the DIY version Firstlight showed looked like it would rip out (just from the pics) and really, i personally see it having very limited advantages on a factory board (easy stance changes is the only advantage i can think of)
i for sure do not think that ICS channels would be an advancement in split tech. i've only once had an insert pack strip while riding and it was some shithouse Kemper back in 1991. 4x4 inserts are not a problem for me, never have been..
i DO get stoked just to see further innovation in splitboarding or attempts at it at least... IMO the Karakorum system is inferior to Sparks, but some people love them and without Ks there may have never been an Edison system... and hopefully Ks will continue to innovate and come with some bomber designs in the future... its all good for the sport of splitboarding..
