As others have said, it's likely gear is not going to make a significant difference.
I've taught lots of people. So many foilers when they struggle look for a change in gear to make their progress better. It's rarely the problem unless they're on really old outdated gear or stuff that's way too advanced. Without knowning much about Uni gear, it sounds like others say that setup isn't bad.
That said, if you are struggling with foot switches, why is that? Do you get bucked off? Is your foot placement inconsistent? If you place your feet pretty well but are being thrown, then put on a bigger front foil, tail or a longer fuse to get more stability into the setup. It has made a huge difference to me. What are the local water conditions like? Is it choppy with confused swell? If so, that just escalates the difficulty.
I've been at this for 8 years now and still don't have tacks or pumping down pat. Still can't ride big swell consistently. But I love this sport and won't be giving up. Sometimes there are things you just need to grind away at. Time on water is the biggest winner here.
Hang in there.
