There's still an idea of wearing the pitcher out in the majors. Of course, if you're an ace throwing no-nos then you can routinely go 110+ pitches per game. Most pitchers go about 60-70. The bullpen is stacked with varying arms and pitch types to throw off hitters their 3rd+ time through.
I ponder GC's choices. It was like a cancer in my major metropolitan area. Within 5-10 years all the mom-and-pop stores with a good solution of beginner and high-end equipment left and these things moved in. Coming from a millennial, it really isn't he way it used to be. Sad.
Slightly related, and assuming you like Blues, have you seen Joe Bonamassa's videos and tours of his collection? Very cool, too. Emphasis on Fender/Gibson, but still quite entertaining. I appreciate player-collectors.
