Stacking With Cup Keepers (4-30-2019)

I bought 10 cup keepers from the Speed Stacks website for about $10 so that I'd have a full set of 12 to try stacking with. After 20 minutes, I really didn't like stacking with them, the upstacks are fine, but the downstacks are absolute hell for me. Oh, well. At least I had a cup keeper for each of my sets.
