My vote's for the Goodfella...balls on the outside are much more realistic, wish more...stunt doubles...were made that way, and it doesn't need to be the biggest in the line to still be bigger than some of your cis-male friends, if for some reason you end up in a "mine's bigger than yours" contest. I don't consider it all that easy to pack, but I suppose it's theoretically possible. And probably easier than anything bigger, unless you're wanting to relive the authentic high school experience of carrying a binder in front of your crotch...
I use it with the Spareparts harness, which has an elastic ring to hold it on, since it's got balls on the outside, you have to squish the base through the ring, rather than putting it in from the back. I don't know how it is with a metal ring harness - metal's more slippery, but it doesn't bend.
