> Thanks Isi. So you mean, have someone else top-rope belaying, or direct belay with reverso onto anchor?
By reverso onto anchor are you implying guide mode? If so then stay away from this as then you have the lowering issue being a little more sensitive.
Basically to top rope you should "clip in" to the equalised loop and clip the belay plate in separate, easy to tie off and make yourself free, otherwise yes get someone else to belay and keep yourself free as much as possible.
Consider getting some cows tails made up, mine are old 8mm rope cut so that I could tie a figure of eight in both ends and one just off centre giving me about 2' and 3' of lanyard each, I attach to my belay loop with a mallion and have two quicklock crabs on the end, means moving around safely at the top of a crag is a doddle and quick.
As everyone else have said, think simple solutions and implement the quickly and efficiently but most important safely, enjoy it too, that way the stress and nerves will be lost in the moment.
