I use my DSA spacebar flipped.
just kidding, though interestingly enough, the DSA spacebar won't work with my spacebar stabilizer. I'll have to swap it out for a cherry one sometime. This shows that the spacing is either very slightly different, or the margins aren't good enough on my stabilizer wire.

Ultimately, getting better molds for SP would be probably the best solution, but it's also the most expensive.
