I was looking at these: Omega Adjustable Reel F/All Univeral KS cat No.455032

And wondering if
a) will they fit in a Paterson plastic tank
b) are they any good compared to the Paterson reels
c) looks like they have the stopper to facilitate loading two rolls of 120 on the same reel.. Possible??

Anyone has a clue?
Looks reasonable value if yes to all the above...
