Re counter balance, this increases the mass of the axis so doubles your momentum, means you get more backlash... (terminology is probably not correct here)
drv8825 do allow for more current and can increase mircostepping to 1/32, this also lowers your max speed. I wouldn’t bother with them unless you have a 32bit controller that can generate the steps pules fast enough to be worth while.
