Newbie climbing question

[Berwick]

I missed this earlier - I'd take the foot ascender off sooner and step up on only the knee ascender to release the Gibbs. Then you only have to take the knee ascender off the rope before descending; should be easier that way since one hand is occupied being your brake hand for the Grivel, ensuring you don't slide down any while removing the knee.

Yes I think that will work, will try it today
