In reply to TobyA:
Simply put... yes they work.
I've been using Crispi NTN Evo Rando's (from Bear&Water) with dynafiddle inserts for the last 3 years.
I mostly telewank for resorts and sidecountry (or molehills in Finland) and for actual touring it's dynafiddles.
Oh, and I would prolly get the Crispi's over Scarpa's (provided they fit). Shiver's might be better comparison to T-X's though.
Some tweakin' is needed on AT-binders though, a shim under the bellows might be a good idea...
