Heh, this is a weird thread.
It starts out like an infomercial, then if you're not careful in your reading, you think it's about scat humor. Then it turns nostalgic with the mentioning of the breaking of the tennis balls, a la the old Bionic Woman tv series.
I had a pair of cheapo handgrips that had plastic handles with a padded covering on them.
I used them enough the covering wore off in places, so I duct-taped them.
Lost them in the move, though.
I think I need to look into getting me one of these.
Thanks for the entertaining thread, Jake.
