[GreenKeys] Casters for M28 Teletype equipment

[W2HX]

Hi all. I am finally getting my new shack together and it is time to purchase casters for my M28 KSR and ASR.  What did you guys end up buying? I think I read that some of you bought the 2" size with no brake.  I am looking at these two currently:

http://www.grainger.com/product/Swivel-Stem-Caster-3A731?opr=APPD&pbi=3A711

The difference seems to be rubber vs. polyolefin.  My new shack has hardwood floors that I would prefer to avoid marring if possible which of these would be better for the floor? Any opinions? 
Is 2" wheel big enough? Did anyone get bigger?

Thanks!
Eugene

I just discovered that W.W. Grainger is closing out a bunch of suitable casters (threaded stem casters with 1/2x13 thread) that will screw into
M28 equipment in place of the adjustable feet.  Prices are less than $5 each.  Some suitable part numbers I found are 3A711, 1ZNK5, 3A732.
(Look in their online catalog to see what you get for those numbers) There may be others too, I didn't look at everything in the catalog.
