My recommendation: rocking kneeling chair. RSI can be addressed with different keyboards sometimes, but as with many other injuries sometimes the root cause is somewhere else, not where you feel the pain.
So if your wrists hurt, don't just look at how you hold your hands. Change your sitting posture, try a standing desk, etc. - there's a chance that just sitting differently will help your RSI.
(This has happened with me. I used all kinds of fancy ergo keyboards, plus expensive regular chairs. Now I use a Varier Balans plus a simple 68% mechanical keyboard, and all my wrist and back problems went away.)
