A lot of the snow that was on Ben More has disappeared, and the Glencoe area is similar, but the cameras don't show everything, and the norther sides of slopes will still have a fair bit, so you'd need to just check it out when you get there and make a judgement.
Ben Cruachan is approached from the southern side, so there's probably not a huge amount, but take care. I'd agree with jmarkb - those slabs will be more of a problem with a thin layer of snow/ice than under a foot of snow.
