Yay for 40%s with dedicated arrow keys! That’s totally what I dig, too. (And currently also trying out 30%s. 
)
Also have one UT47.2, one Vortex Core (was my first 40%) and multiple MiniVans. I also have one Keebio Fourier which was my first split keyboard. I usually used it fitted together, not split… Oh, well. 
Don’t have Plancks as I’m not that much into ortholinear layouts. Have the Zlant instead. (And I love the idea of an semi-staggered, semi-ortholinear layout like the Alpha28 has. )
Definitely need to make a group picture of my keyboard family once, too.
