Hi I was up two weeks ago. The ascent up the back of the Corrie was very hard but once at the top the going was fine.
Care needed on the path coming down from the top until you get in the woods, as snow had fallen over it making it quite tricky. I was lucky because there were a few people ahead of me and I was walking in their footsteps.
I only had a walking pole and Decathon cheap walking boots so you should be alright.
