Excellent choice, sir, and oh- how much do I want one..?!
I'd thought that the Speedys were well replicated, but what do I know? I ended up with a 2531.80 SMP, as there's not one replica (other than the coveted old factory version) with the correct HE valve position. Gets more wrist time than any other!
I vote for the SMP 2531.80.00 It's a classic now, and will ever remain so. For wrist comfort and balance it is second to none. I can't say the same for the PO, but it is a personal choice (maybe that's why they still make so many variations). I also rend to agree with the school of thought that favors the 1120 movement (and original external design with the shorter hands, sans red paint). Nuff sed..
