I have used the Paterson 5 roll tanks ( 3 rolls for 120 ) for over thirty years without problem. Especially the later type with the wide top with bayonet lock is very convenient and easy to use. The filling and emptying is much more easy and rapid than with the old design with the screw on top. If you are just consistent with the timing, start when you start filling and stop when you start emptying or start when you finish filling and stop when you finish emptying, then you shouldn't have any problem.
The only thing that can cause some stress is if the rubber lid doesn't go on leakproof at once. But on the other hand, that is independent of tank size.
