I find the Tension Watch to be the most useful to mantain the same tension in all of the screws, and also to keep/check the tuning through a session.
I like tuning the drums a bit lower and muffling the resonating head, BUT...
I suck at tuning drums myself, specially when I must do so from scratch. In terms of the Tension Watch, do you guys have any observations on tension samples (different than those at the Tama website) as a starting point?
