Actually, I have done this exact test on those three frame before and while I agree with you about the PS85 and K90, I felt the BLX90 was notably different in this regards. It felt more 'pingy' (metallic, less dead - however you explain it).... Nothing compared to a tweener frame but moreso than the other two.
