I have one of those chain tools and I like it very much. It is small enough to include in my portable tool kit for the bike and I have had need to use it on the road.

The crank tool is a must have for anyone building a bike with a shift kit imo. I find myself taking off the cranks for all kinds of reasons. Easier access to other bolts. Checking tightness of bottom bracket parts. etc.

Put me down for a couple of the teflon coated cables. Sounds like an excellent idea.
