Thanks Nicko,
That was the post i read

. The review talks more in debt in comparison with JP and only briefly mentions the same shape as the triwave. So i'm curious for more info.
I've got a review of the 85 newer model. It's in German though. Maybe you can get it through the google translator and get something out of it. My german is only so so. The review mentions that the shape remained the same as the previous model:
