Hi. Well, I started training in my 40s, so while I was willing and able to learn breakfalls (because I believe that its important to be ready to take any ukemi that a situation may demand), I've been very interested in softer versions. Where I used to train, a sempai sometimes gave classes on softer rolling ukemi. I also bought (and recommend) volume 1 of Donovan Waite's Ukemi videos.
I like doing a softer, rolling forward breakfall thatnot only cushions better but lets the rolling motion bring me back to my feet more smoothly.
Also, instead of backrolls or back slapouts, I have been using the rounder back ukemi he shows: either across the shoulders, turning, to come back up, or turning the backfall into a forward roll.\
Definetely kinder on the joints....
