The last time I restocked pots I ordered a pile of CTS pots, and they've turned out to be just the opposite - too stiff for some users. I've had to replace pots twice for customers who were dissatisfied. Usually, the Bournes pots are the stiff (or smooth, depending on your desired feel) ones, the Alphas are so loose they feel worn, and the CTS are just right. So, who knows? It seems to come down to the grease they used to lubricate the armature. If you open up a stiff pot and clear most of it out, they feel better. Loose ones? I don't know, as I'm not sure what grease wouldn't be detrimental to operation over time.
There's essentially no power dissipation requirement in this application, so 2 watt pots would seem excessive, but they're mechanically large enough to take the abuse guitars see. Not sure smaller ones you have would last as long. I know they're a helluva lot easier to break on installation - be careful torquing on the mounting nut. It's easy to snap the threaded barrel.
