Dual Z single stepstick

I am pre thinking how I am going to setup a hypercube evolution build I hope to make happen soon.

I want dual Z drive, I am likely to use an MKS Gen 1.4 board like I have in my baby cube I use now.
I have TMC2100 stepsticks and love them!! But they have pretty low current capacity...

IF I run dual Z motors in parallel on one step stick I think I am unlikely to have the power I need....

Suggestions?

Oh I plan two extruders so I cant use dual drivers on this setup.....

Maybe I should look at a Rumba so I can run six step sticks....

What other decent boards are there with six step sticks... Seems like there is always something I don't like on every one I look at....

There's RADDS running well on RRF. The TMC2100 is even quieter on an 32bit board than on 8bit.
Why not use a single RAPS128 driver for two steppers, they are quiet too and have plenty of power.
Z axis doesn't have to be quick...

Thanx for that info...

The more I look into this the more I think I may bite the bullet and go for a Duet3d Wifi soon... Well around end of May kinda soon as they are so $$$
