To all (Alpine Ace, Trench Digger, Lord of the Ruts, Groomer Grommet, Carver Extraordinaire) ..... mucho gracias ..... though to be honest, me missin havin' the heart to actually dremel my Raichle's.
Decided mods for now:
1) looking into replacement tongues for added flex option(s), presently have the rather still "racing flex";
2) the comps came with three different options for liners: a standard liner, a Thermofit liner, or a Thermoflex liner. Contemplating adding footbed and upgrading to heat moldable liner from the existing Thermofit liner. Though I do like the attached velco power strap;
3) Concerned about the boot/binding interface. Any suggestions for replacement toe and heel pieces? Interestingly enough, some have experimented with attaching "vibram" hiking soles.
