My dad's a Topre man. He mainly uses a Realforce 104UB w/ all black blanks like a badass, but has a HHKB in all-white w/ blanks he uses for travel. I told him using blanks makes him cooler, which I think no one can deny.
As an MX man it's my fault for recommending Topre after evaluating his needs, but he seems to love them. Hell, he's written three books with them over the years (damn has it really been that long already?)
