Battlestar is great kicks using a barbell up a gear or 2.
Awesome that it gets in the hard to get corners in the ankle and upper arm. The grippines gets in.
Good to have the 2 sizes as well.
Hit the finishing parts of my ankle that nothing has been able to get into.
Definitely goes well with the supernova and gemini.
Each having places that bring out the best in the tool.
I wouldn’t want to be without any of them, and I use YTU Therapy plus ball for some aspects.

Definitely think there is a progression with what tools you are using where and when. You don’t want to overdo something same as overdoing something in training.
