Well, after a ridiculous amount of comparing measurements and so forth I think it's come down to these Samurai S512XX BCIIIs.http://www.rakuten.co.jp/d-stock/540681/617425/
They look like they are a very slight bootcut, which I think will work well since I'm pretty tall (I am finding that the tapered leg on my SC Okinawas doesn't work so well given my height). The only question I have is the rise, which isn't listed. I am assuming since they are a mild bootcut the rise will be very slightly less than average.
The alternative is the SD-105, which I like because it's a lighter weight and seems to be a darker color. The SD-105 has the exact measurements of the SD-103 except it's 1cm wider at the bottom of each leg. The concern with these is the rise, though. At 25.5cm for a size 32 it seems REALLY low rise. Maybe someone with an SD-103 can comment.
