I'm honestly not a big fan of his review on shafts...
I just don't think a firm stroke today is the same as a firm stroke 2 years ago, the comparison isn't that accurate IMO
But I guess that's all we got unless we can get a robot
Yeah I had a little back-and-forth with him on one of his YouTube videos in the comments. He always says that squirt is larger with higher speed, and I linked him to some of Dr. Dave's tests showing that speed doesn't increase squirt, and instead it's just curving back more with slower speed. He didn't want to hear anything about it.
Oh well, it's better than nothing, and definitely better than other cue reviews. In fact his channel is the only one I'm aware of that actually has squirt tests for a variety of cues. Kudos to him for that.
