For the type of playing that I usually do, a single ply coated is my go-to head. Sometimes with a dot underneath, sometimes with an overtone ring, but almost never two ply. I don't play hard enough to need the durability, but I have used a Remo coated Vintage Ambassador a few times and it can work well for my playing style.
HalldorL said it for me as well.... I prefer the tonality and crispness of a coated single ply. That said however I also use a Remo Ambassador Fiberskin (1 10mil ply and 1 3mil fiber) on several snares for the additional fat back beat muffling with out killing all the resonance of adding a top ring.
Standard single-ply coated, it’s been some time since I used Fiberskyn Diplomat for some brush gigs or thicker single-ply (12mil.) for a darker sound. I found I don‘t like 2ply, including dots, for low volume playing.
This is what I have on my main snare. However, I do not have the same head on any two drums in my (small) collection.
I've got a G1 Coated, UV1 Coated, Remo Fiberskin, Aquarian Modern Vintage. That's just the ones I can remember off the top of my head.
All are coated in some way. I just like the tone I get from coated, plus I never know when I will need brushes. Smooth/Clear just doesn't work for brushes no matter how you play them.
Mostly single ply coated, but am using a Vintage Ambassador at the moment, which is a 2-ply coated. Have a few coated/dot heads, but will use them when my other heads break or become untunable. Coated rules for me.
It depends on the snare, but generally it's either a Remo coated vintage Emp, coated Amb or a coated Dip. My Pearl 14x3.5 maple FF loves the Emp, my 64' Acro loves the Amb, and my 20's Ludwig NOB 14x4 loves the Dip.
Piccolo snares: single ply coated
Wood and Supra: single ply reverse dot
Brass: two-ply coated
Steel: usually single ply coated
I’ll occasionally use a small DrumDot way up against the rim depending on the style of music. The single ply reverse dots allow me to play brushes when needed but also provide great tone and tuning range for a variety of styles.
