DA-only revolver for trigger training?

I bought a lightly used SW 929 9mm (6" barrel) revolver somewhat on impulse (before Newsom's latest 2A tax grab kicked in). I wanted a good revolver (among the few available in CA), and 9mm is appealing because it is cheaper and I don't reload. Besides the hassles of moon clips (loader / deloader on the way), first time shooting was fun and of course now I want it improved and accurized.

The stock trigger is heavy in double-action, more than my 8# trigger gauge - maybe 10-12#, with some stacking.  Single action is a very nice smooth 4# pull, and I could learn to shoot it SA.  But it seems the revolver crowd prefers to shoot double-action, with modifications such as bobbed hammer, lighter springs, etc, to make it work.  It has a titanium cylinder, ostensibly to reduce rotation moment for faster rapid fire shooting.

Optimizing for double action would make it DA only, like this:

For those who shoot revolver, do you recommend going DA only? Does it help improve trigger skill, or other benefits?

Thanks

I shoot a 9lb DAO trigger on my revolvers, it is fun and different but unfortunately it doesn't automatically grant one awesome trigger control when going back to a 2lb SA trigger. I admit, initially I kind of hoped if I practiced this way it would make everything else seem like "easy mode" but it does not. It's just different.

For context, I am classified Sharpshooter, I often but not always shoot low Expert scores in the .22 part of the match. My PB with a target .22 autoloader is 829 and my PB with the .22 DAO revolver is, I think, 821. So, pretty close. I only shoot metallic sights.

Both SA and DA action are valid approaches. Regardless of the approach you use, revolvers can be a significant challenge, but very rewarding. I shoot SF single action and shoot double for sustained. That said not all DA triggers are created equal. Some are really good others leave a lot of room for improvement.

Among top tier revolver shooters, it’s mixed . 
The PPC guys have to do DA, and they get an extra hand and barricade to do it.
