Well I got my hak a few days ago. I ordered the 8oz poly/cotton hak from Bu Jin Design. I really like it, and I think I'll be ordering another one from them soon.
On a side note though, had some troubles getting folded, even with the help of people in class. It seems the Bu Jin hak is made slightly different from the "normal" hakama you find. So, if you think you'll have time Jun, would love to get a small Bu Jin hak folding lesson from ya at the seminar.
