Recent air combat sim recommendations?

Thought I’d re-post this question here in case some of you don’t venture into hardware sub-forum.

I decided I want to get a trackball mouse that I can set on a small barstool chair right next to me so I can do some mousing while I’m in VR for my flight sims. I’ve never had or used a trackball before and I’m not sure what I would adapt well to. So far I’ve looked at Kensington and Logitech’s but have no idea what would be best.
