UK PAYG sim info re. cloning

[spraky]

Strange question I suppose, but I don't live in the Uk but I would like to buy a PAYG sim card for occassional use when I visit the UK.
I would like to have it on my sim-emu 5.00 and was just wondering which sim would be the most likely to extract ki sucessfully.
Also does any UK PAYG sim, offer roaming.

I have only ever managed to clone ORANGE sim cards. Has anyone else in the Uk cloned any of the other networks?

so far i only successfully clone an Orange payg sim card. other network sims were not successful....
