I mostly spend my time on VAF reading and being amazed at the vast amount of incredible knowledge here, but having been through this problem recently myself I feel I might be able to make some useful comment on the issue. I am extremely right handed. My left hand is for opening jars and carrying bags, and that's pretty much it. It doesn't get a lot of use in anything requiring precision.
I got my start in flying as a kid with flight simulators, and have been involved with them my entire life since then, so I probably have something like 25000 hours of stick time on them, and all of that was with a fighter-style joystick and throttle quadrant setup, with the stick in the right hand and throttle in the left. Sims by their very nature are all hypersensitive, just like RVs, so it's good training. In the real flying world I came from a few hundred hours of 172 time, until I purchased my first airplane, an RV-7A.
Flying a 172 with my left hand is no issue as the control movements are very large and often require quite a bit of muscle, but transitioning into flying the the RV7 with the stick in the left hand, and making movements of only a few millimeters at most, I had nothing but problems. I was finally able to reach a point where I felt I could fly safely, even in crosswinds, with my left hand, but even after 40 hours or so I just wasn't
happy with it. I had to actually *think* about every single move I made with the stick, whereas with my right hand everything was muscle memory, instinctual and smooth.
Someone here on VAF described it best: "If you're right handed can you brush your teeth with your left hand? Sure. Can you be effective at it? Sure. Will you ever be as good at it as you are with your right hand? No."
After reading that I made my decision to move to the right seat. I ripped the highly left seat-centric panel out (all instruments were on the left), completely redid it, taking the opportunity to remove and replace some old hardware, and installed right side brake pedals. To preserve the airplane's resale value I strove to keep the panel as ambidextrous as possible, by placing everything of importance in the centre, and it's now perfectly flyable from either seat as pilot in command. I've included a pic of the layout.

Within two hours of flying right seat and right hand stick my landings improved five fold over what I was able to accomplish with the left. Everything was instantly smoother and every manoeuvre felt precise and great. This was the experience I was sorely missing, and I adore the airplane now. I now have about 100 hours in this configuration and I'm never going back. If I ever buy another RV I'll be doing this procedure all over again I'm sure. Maybe one day I will have the time to build one!
Don't worry about getting used to the sight picture change from flying right seat either. I got used to it in about 2 or 3 flights. I was recently flying left seat in a Marchetti SF260, and now left seat actually feels a little strange to me, hehe, but still good. Anyway, it's an easy transition. Instructors do it all the time.
As for left hand duties I have no problem using the dynons or radios with my left, even in heavy turbulence, as these are still simple single axis coarse finger movements, unlike the stick, despite the tiny buttons and knobs. As for writing notes I just put the stick in my left hand for those moments. That hand is smart enough to hold a level flight attitude at least.
The only inconveniences of the right seat are not being able to see the elevator trim tab position easily during the preflight check, so I just sit on top of the seat to view that, and I have to reach across any passengers to operate the tip up canopy lock, but they never seem to mind.
Apologies for the slightly long winded post!
Cheers.
