I haven't found a problem with 14x12s! I neither find them unwieldy nor do my bees have trouble drawing foundation,this they do with ease including adding drone cells along the bottom bars!
In my previous post I did suggest placing foundation above a QX during a honey flow to facilitate straight comb!
I did this with BS boxes ,not because of any 'difficulty but rather because bees presented with foundation for which they don't have an immediate use for mess around, draw in random patches chew holes through it ETC.
Like children they need meaningful occupation or they become mischievous
