Well it was routercnc who said stick with the 16mm due to the added intertia of the 20mm. The man has built four of these things, he knows what hes doing.

I'm saying they'll work, but realise that they'll limit your rapids more than 20mm will. Personally I'd be more than happy with 10m/min rapids - You'd need some pretty strong motors to get up there anyway with a 100kg gantry.
