OK, this sounds like a fun game… I’ll play 
I am in Zone 5b- Northern Colorado Front Range
Apple Scion wood:
American Summer Permain, Benoni, Chestnut Crab, Claygate Permain, Clark’s Crab, Esopus Spitzenburg, Gray Permain, Hudson’s Golden Gem, Lady, Lamb Abbey, Milo Gibson, Orleans Reinette, Pinova/Pinata
Pitmaston Pineapple, Rubinette, Spencer, Sweet 16
These were selected mostly from recommendations by Roland Jacobsen, Tom Burford and Oren Martin, plus reviews on Adam’s Apples, Orange Pippin and Pomiferous. And @clarkinks and @NuttingBumpus
Pear Scion wood:
Ayers, Beierschmitt, Harrow Delight, Magness, Seckel, Warren
These were largely selected based on Growing Fruit folk, particularly @clarkinks @mayhaw9999 @Fusion_power and @belowtheterrace
Haven’t decided yet which apple/pear varieties are field grafts and what I will bench graft onto rootstock. (G-935, G-214 and OHxF 87)
In addition, I have ordered the following trees: Black Ice and Lavina Plums, Summer Rambo Apple, Warren Pear (on OHxF333), a 4 in 1 Pluot and PixZee and NectaZee miniature stone fruit. These last 3 are not zone 5, so they will be going into Air-pots and stored in shed over winter.

GrowingFruit has been a great resource this past year for selecting varieties, I appreciate all the help! I take sole responsibility for the fact that I am clearly buying way too many fruit varieties and have little idea where some of these will go!
