If it turns out that is the only economic choice [and it looks like it
is so far], then yes. I just prefer to standardise hole sizes where
possible, and I use 0.8mm normally.
That said, I have found another 0.8mm supply on taobao, chances are
probably the same closer-to-0.9mm ones, but I'll maybe grab a couple
hundred in my next order and see anyway, probably $3 or $4 USD.
