@nreid77 there is a good thread here in case you haven’t seen it.
My daughter uses omnipod and it is significantly better than MDI in terms of her average time in range.
I think it would be unfair to offer an opinion on t:slim as I have no experience with it. I have looked into changing but can’t find a good reason. the main reason not to change would be that omnipod seems to work well and the tubing.
I hope the class goes well - ask plenty of questions
