If I'm correct, the BW uses bar stabilizers instead of Cherry MX stabilizer switches. That could be why you're having issues with backspace.
I not really sure what exactly is wrong with BW's stabiliser. Other board with such(Ripster normally call it Costar style) stabiliser, especially Filco are doing perfectly well with it.
For personal experience, I got a Keycool 87 with similar type of stabiliser. To my surprise, the "Right-Shift" is very nice to press and even feel exactly the same as other stabiliserless modifier keys such as "Alt" and "Ctrl". This make me feel want to remap the "Alt", "Ctrl" and "Shift" into arrow keys(similar to that of Poker) as it will be bigger.
BTW, you will shyt bricks when you take off the spacebar and have a look at the stabiliser of spacebar.
