I'm sure glad that you will try out a different swing as I would really, really hate to hear of you (or anyone else for that matter) having a serious accident with an ax. I am even willing to go so far as to say that you might want to dump the Fiskars in favor of another ax that you feel safer with if you cannot find a swing that works for you.
First and foremost, Stay Safe!
It's works too good to dump. I split a bunch more with it yesterday and found out that I already was using your technique to make sure it goes straight down. I see that I'm sort of benting at the hips to get the tool down lower so it can't make that arc or circle into the foot.
The combination of the short handle, a high swing from the shoulder, and using a splitting block is a dangerous combination with this thing. It really should tell you that.
