Anti-Puncture Tyres At-a-glance

i wouldn't touch a dahon with gloves, why on earth would you run 50? is that a rental thing or sth? anyway, thanks!
so steel bead is a nogo and skidding a bit is a must, so that a £26+ husk at the back seems more than unlikely.
i think, i narrowed my 'faves by the facts™' down to 3 or 4. euphoria decreases, where likeliness due to the price drop increases down the list:

1. panaracer ribmo, folding 23c, £30,-
   
   
   
   

I am convinced these tyres feel slow. I recently put some 35c folding Ribmos on in place of 35c Randonneur folding and it definitely feels slower. I should have done a rolling test thing but can't be bothered now!
Anyone else use Ribmo's?
