Hey guys, I'm gonna get an insulin pump, but I don't know if I should get the T Slim x2 or the omnipod, so I have a couple of question that I would be very grateful if someone could answer

1) If I'm gonna change the cartridge, can I take out the remaining insulin and put it inside the new cartridge? I don't want to throw away the remaining insulin in the reservoir when I have to change it, so is it possible to do this in any of the 2 pumps?

2) Let's say that I decide not to use the insulin the reservoir, how long will the insulin last in each pump before it stops working properly?

3) I've seen waist band for the tslim x2, how comfortable are those? Is it worth it? Or is the clip case enough?

4) With the omnipod, if I'm using a dexcom g6 cgm, can I see my BG in the app or in the pdm? If so, is it possible to make a closed loop system like in the tslim x2?

5) I'm not very familiar with insulin pumps, but both of them deliver insulin continuously throughout the day, right?

6) I usually go to the gym to lift weights (sometimes I perform exercises like the hip thrust or weighted crunches) which one would you recommend to me based on my lifestyle?
