nice pair, the ti irid is a good pairing choice (and logical) to the Ti frame. seems the ti finish varies quite alot, yours is abit later on in the run maybe? hence the similarity to the later gens? either way, nice grab. Take care of the serial area, Ti's tend to fade serials LOL
edit: looking back, is your Serial laser engraved? because the earlier ones were not, they were almost like a print, hence why they could fade..
