Both the Angel and Wilson (Black Widow) tabs are excellent, I own both and currently slightly prefer the black widow. This is largely because it has an extra layer of material that makes it feel nicer for my draw weight. If i could figure out an easy way of adding a layer of oberon to the Angel without having to restitch everything, I'd likely be using that.
Theres a store in Japan that sells different versions of the Angel tab.
Archery Equipments archery-direct. Pretty much every combination with/without finger spacers, chin platforms etc. Though the platform and spacer are easy enough to remove if you buy the full model that seems to be stocked in the UK.
