I absolutely hate the choice of drum heads.
Why? That's a pure jazz kit, meant to be tuned on the high side. Maybe the owner needed a little more attack out of the drums. In which case, the choice of the clear pinstripes is a smart pick! Pinstripes can make a drum sing too! Depends on what sound you're looking for. But it wasn't an out-of-hand 'bad choice' of heads.
That said, I agree with you that coated heads would be better sounding and more appropriate for a jazz kit especially if you plan to use brushes. I just thought your call on the guy's choice of heads was a little harsh... I can see situations where he might legitimately prefer the sound of the pinstripes.
