Hi all. Currently in the market for a cart bag having purchased a Powacaddy CT6. I believe the fitment to which is the same as the current FX range.

I am between the Stadry 14 and 15 as well as the Premium Stadry cart bag. Can anybody comment how any/each of these fit on the current line of Powacaddy trolleys. Are the bases in any way compatible with the Key Lock system?
