Hello Again Greg,
As has been mentioned by others there's a load of ways to get a "Choppy" finish from out of balance wheels to bad bearings, Incorrect wheel selection incorrect feed rates, poor dressing, etc.
I can't think of a better way to store wheels other than horizontal in a cabinet, maybe heat would help a little, maybe a lot, never tried it, the reason for the old hang'em on a peg method is simply because it's really space efficient and quite OK as long as they aren't there for decades, problem is we all buy a lot of old gear and it's often left as it was used, as I did through a lack of planning, I walked away from a shop at the end of the day and that was it, I thought I'd be back a weekend later and all of a sudden fifteen years, a wife, two kids, moving to a different country, two businesses and four busted vertebrae later, I realised I left this stuff for others to maintain and they hadn't, It happens and that's why we get this stuff cheap I suppose.
The good news is there's loads of easy fixes to try before you're stripping the bearing cassette down and spending cash on high grade bearings.
No1, Really get your dressing and balancing straight,
No2, Experiment with feeds and speeds,
Maybe then look at wheels at this point, wheels can get expensive and if you've not dressed it properly no wheel will work properly as is true with balance.
When all else fails strip the bearings but remember cleanliness is critical and that includes lubricants (no shortcuts)
Oh and always grind wet, I have always had more sucess with a wet wheel whether it's off hand, cylinderical, T&C, threads or surfaces Heat is the enemy.
I hope this helps
Best regards
Rick
