I have recently tried the silicon monthly toric (Bausch and Lomb Pure Vision) soft lenses from Specsavers since I have astigmatism too (up until now I have been using the ones that don't correct astigmatism since they can still correct me to 20/20 or something like that, I'm no optometrist either ha ha).
To be honest, don't know if I was given a dodgy pair or what, but they seemed really uncomfortable - within a few hours my eyes were quite bloodshot so Specsavers have put me back on the others. I still want to try them again though - since the vision was that extra bit sharper.
Let me know how you find them - if they are ok I will revert back.
cheers

P.s. the normal silicon monthly all day all night ones seem fine when I'm flying - I carry some eye drops around with me just in case my eyes do get a bit dry as you can get some that you are allowed to use whilst still wearing your lenses.
Gee my English has got bad - such long sentences !
