Undoubtedly best as a sloper - but it was the only hold I had on short notice

Yes I agree.
I try to keep the fingers as relaxed as possible, and use them only as much as to stop the palm slipping - with the palm taking as much of the load as possible (sort of like heel hook, but using the palm - or like resting on a hand jam). Otherwise I'm not really sure how it's not just the normal way you'd grip a hold instinctively?
