Having bought some Titanium from the US and with CP's help and information I have made a Flissure Clone and the Infernal insert for wood. Much better in Ti than the previous efforts I made in Aluminium.
In alcohol mode I use a FeatherFire stove.This is very frugal on fuel mainly I guess to the accurate construction of that stove, better than my efforts with several alky stoves. I previously used the Mini Zen chimney stove. There is not a lot between the two re boil times but with the FeatherFires simmer facility and the ability to be able to put it out and reclaim fuel makes it a fine light weight set up.
I have used several types of Sealskin,I think they are best to keep your feet warm on winter bike rides.Though your feet have to be warm first
I already have a lighter sock for runnning and have walked in them. The main drawback for me was that being strong and stretchy they scrunch the toes up and the thickness might mean you have to move up a shoe size,neither of which is desirable.
