In House just dropped a whole slew of Banana crosses but they're pricey. (I cant justify more than 150 for any seeds so I wait for sales when buying In House.)
Swamp Boys, Green Team and Oni have a few that look promising. Banana Puddintain, Banana Fruit Bound and Sour Banana Dubb.
Rado dropped a few a while back to that may still be available.
I picked up Nana Pie and Banana tree with a few others from the last drop.
My Banana Trees are just now entering veg so no reports yet on terps but I'll throw up some pics and updates in the Cannarado thread as things progress.
Jaws usually puts out good crosses but I don't have any personal experience with em. I'm sure others will be along with more recs.
You should be able to find a lot of crosses available using Banana OG. But to coax out those terps you really need to find the right pairing.
Good luck on your hunt
Oh, and nice bike. Dyna?
