I had real problems with keyboard height when I had unorthodoxed finger positioning (I didn't used my pinkies nor my right ring finger). Before using mechanical keyboards, I always used low-profile laptop-like keys. When I needed to reach for a key, I would slide my fingers gently across the surface of the keys and feel for the key I'm looking for. You can imagine how this would be a big problem when using mechanical keyboards because sliding my fingers on most standard-profile mechanical keyboards would mean I'd be hitting the edges of the keys and accidentally pressing those keys. This was my exact problem. I had to use heavier keys to reduce the typos caused by my bad typing habits.
I practiced for a year adding my right ring finger into my typing. I was able to type significantly better on lighter keys, but I still wasn't able to type well on keyboards with odd layouts or really high profiles (Realforce 104UG Hi-Pro). I've been practicing using all my fingers for a little more than a week now, and already I see less typos. Utilizing all my fingers when typing also has made every keyboard I type on feel better. For example, Topre keyboards just feel way better now. It feels like I'm getting a longer and spread-out massage on my fingers because all my fingers typing away as opposed to just a select few.
