Idle thought.

Is it logical that movements with solid banking have a quieter 'tick' than those with banking pins. I am quite impressed with how quietly my STD 96-4 ticks...it has solid banking. The AS1187 is more audible with banking pins.

I don't think that is so. I would have thought it could be to do with the case a thicker case will be better then a thin one. A square case can never be as secure as a round one.

No, the 'tick' sound of a watch is actually a combination of five different actions and sounds from the escapement, starting with the impulse pin striking the slot of the pallet fork, next is the escape wheel tooth falling off the locking plain of the entry pallet stone and striking the impulse plain, third is the opposite side of pallet fork slot striking the impulse pin, fourth is the escape wheel tooth hitting the locking plain of the exit pallet stone, last sound is the fork striking the banking pin but there are as you can see lots of actions taking place to create the sound that don't include the banking pins.

Hope this helps a little, the escapement is a fascinating subject.
