Then there are two of us on planet Earth.
I started the same way but the quest led me down a different path.
For the most part you have chosen varieties that i have grown but pulled out… in lieu of the more uncommon and hard to find varieties.
I guess kind of like the pawpaw guys, the persimmon guys and the fig guys… it starts to become a bit of an obsession to grow the oddballs eventually… i hope that you dont get the bug like me and are satisfied with what you have.
Since you seem to enjoy videos and learning… join the Blackberry Growers group on FB and watch all of Jim Elliott videos from 2019ish… i thought they were all entertaining and he is very educational to just starting out. He shows the differences in trellis as well as how important mulch is as well as tying and tipping. That is if you want a somewhat compact plant that is highly productive and easy to manage.
If however you want to do the opposite then you can look at American Berry Growers and learn about not tipping and training all canes horizontally. This will give you more production per plant…but you will have to space plants much farther.
Both to me are similar in the math. But Jim’s way i think is much simpler and much easier to manage and the most useful of space management.
I like the U of Maine extension videos on Youtube… for rasps. They make the most sense to me.
Not sure if you have seen the thread on here about blackberries rasps and hybrids…but i show alot of different techniques on trellising and pruning that i have found in my journey. As well as talks of various cultivars.
