Just a thought though. On my last cutaway I couldn't get the cutaway hande off easily, as I hadn't released the velcro for a few weeks and was also spinning. I had to use two hands on it before going to my reserve. It did mean I fell away from the main slightly unstable but had no problem getting the silver handle.
My preference though is for getting both hands on one handle each so that, all being well, the reserve can be deployed as soon as the main has gone.
