Thanks for your comments.
Aldermog: is the left hand the UK nearside or offside and is it a one person exercise ?
I'd been think about replacing the 'Fiesta' plastic handle with a cord landyard. Less elegant than the handle but would avoid the teeth clenching, will it wont it, moment when you try to release the catch.
I had a Simmonds hood on my previous Morgan. Prefer the factory easy-up hood in every way apart from the plastic handle release.
