I haven’t gotten all that much due to poor (insufficient) pruning/thinning, rot, and animals.
Netpune- I’ve actually got this pruned well (I think), as a nice column with a few branches at the top. But it has still been completely wiped out by rot for the last few years, even with multiple sprays. I’m replacing it with a jujube this spring as I think it is a pretty good location. There is a little shade in the morning, but hopefully that will go away when a neighbor cuts down a tree they have been talking about for the last 6 months or so.
Joy- I don’t remember any issues other than animals with this one (even though it isn’t in as good of a spot as the others), so this one seems like the least bad 
Faith- Gets a lot of black rot. But it also grows vigorously and densely, so I’m going to try heavily pruning it this year and see if that helps.
Gratiude- This one is a bit winter tender for me and has dieback. It also grew very dense bunches, which gave me problems when something started damaging it.
Hope- Not bad, now that it has grown tall enough to get to the sun. Reasonably productive, but a lot rotted, even with a decent pruning job. I have some trouble knowing when to pick these.
