Old leather saddles

Short answers
Stelvios are very good tyres, if a little heavy. I had the wired Stelvio Plus variation on one of my bikes for 2 years and never had a puncture. I don't think they make that model anymore, just the regular ones.

I got some of these in the Planet X sale last week, but AFAIK they have been discontinued, so it'll be the last of their stock - http://www.planet-x-bikes.co.uk/i/q/TYSCSTPLF/schwalbe-stelvio-plus-smart-guard-folding-tyre

EDIT: re-read the OP to see a verdict was wanted, not a source, i'll leave the link in for anyone else though
