Matching Roberts Track and Road bikes

How practical are tubs for training / winter use? (serious question, if anybady uses them for this)
I've never used them, but I imagine they're a pain to fix when they puncture.

I started using tubs about two years ago and I am a big fan. Obviously the gluing and mounting is a hassle, but once you've done a few, repairing punctures is not a big deal.
The best thing for me is how easy it is to deal with a puncture on the road - peel off the old tub, put the spare on and add some air. I might be kidding myself, but I feel that the general ride quality is also superior compared to similarly priced clinchers.
All my bikes are on tubs, from that Roberts down to a fixed beater, and it hasn't caused me headaches or extreme spending.
