Hey easyrider, good choice of heads. I recently replaced my 2 ply Remo Emperors with Evans UV1 which are 1 ply. They're designed with a very strong coating that doesn't wear away easily and after several weeks of use, mine still look brand new. Highly recommended the next time you're ready to change heads. I remember Hayman drums. Nice vintage
Also, I had considered the Drumdial but bought the Tune-Bot a few months ago. Where the Dial gives even tension, that doesn't necessarily equal even pitch. Though I'm sure you've got a very nice sound now.
But what I like about the Tune-Bot is that it actually tunes the heads by frequency, and octaves if you want. It just clips onto the rim and doesn't need moving around the drum. Though I've tuned drums by ear for years and get a good sound, the Tune-Bot speeds up the process, plus I can save the settings and get the same tuning every time. I've got a Tune-Bot app on my phone with frequency settings for different size drums. You should definitely get one! I'm sure you know this, but if you prefer more resonance, then tune top and bottom heads the same. But I generally tune my bottom reso heads a bit tighter to get a nice dip in the sound.
