All of my hand gun loads are moderate to warm, and all I use in them is Unique.
You seem to like the original "Powder Trinity". I also use a Powder Trinity but it's slightly newer but just as good or better IMO. My Powder Trinity is W231 (HP-38), W540 (HS-6) and W296 (H110). Like you I try a bunch of different powder but when they're gone I always come back to those 3. So, I quess the answer is, I also load older powders more than new...I was working on the bench yesterday and noticed that most of my powders that I am using are older. You know the "classics". Bullseye, Unique, 2400 etc. The ones I am burning off and not replacing are the newer powders. Lil-gun, Longshot, etc.
When it comes to rifle powders I use older time test powders too. 4198, 3031, 4895, 4350 and 4831 are the powder most used in my reloading. Although, I have given AA5744 a try in the 45-70 in place of 4198 and I think it's a keeper!!! The recoil feels slightly different and it's a little smokey so it's a little like Black Powder which is nice in the Springfield TrapDoor... It's the one newer powder I think might stay on my bench.I should have said that in Rifle, I use the IMR's. 4895, 3031 and 4831 are my primary powders.
