I had purchased - and returned immediately - a 52100 Ultimatum from the first batch. One of the things I didn't like about it was that it really wasn't a very good copy of the KS. Sure it was flat from the heel forward to about the 1/2 point - DEAD flat, which too me is too flat, and the KS and Yusuke KS-clone are not - but at the last bit towards the tip I thought that it turned upwards too much. Maybe I'm remembering it wrongly. PT - can you post a comparison shot of the tip profiles?
