DAVID:
If so, then this screw on version could also be used for the 18,500 as to go for the 18,490 instead of the 18,350 when "kicked", RIGHT ... !?
Just thinking out loud here, but How great it would be if this 'add on' included the possibility to choose to have the kick or not... Meaning...
A 18,500 with this add on sort of extension cap/ button could be used to "kick-improve" your unit with a 18,490 IMR and, at the same time, as an alternative: to keep it still fully mechanical, but with a 18,650...!!!
Now, THAT would be sooooo cool...
And the minimal look wouldn't still be compromised... We could really use your magic here David...
Just saying... =)
