I don't know which reeds are the best, most compact or economically priced, but, like you, the knowledge is out there & it would be good to have it shared.
What I can say is that any packing will be necessitated through the 'depth' of the reed assembly, bore diameter, boost port size radially & frame/inlet manifold proximity.
IMO it cannot be said that you will need a packer of 'x' thickness until all of those considerations. In any case, I end up making my own packers from Tufnol or alloy plate as I'm so used to having to fettle everything to fit that I buy, may as well accept that you've got to get the tools out.....
