Open Pros are nails. Seriously. I haven't ridden or built A23s - I'd like to though. Chrinas are basically a copy of the Open Pro design (near-identical profile, double eyelets) that use a cheaper aluminium alloy, and more of it, to compensate, hence the c. 100g of extra weight. Strong, certainly, and a great budget choice, but as far as I can tell they are no stronger than Open Pros. Whereas Open Sports are definitely less stiff than OPs (but still absolutely fine for most riders).

Anyway, it's moot - LFGSS has decided: A23s.
