That probably depends on your insurance company. Though the upfront cost is lower, the monthly cost of Omnipod supplies are more expensive than Medtronic, so you probably have to find out if your company will pay for the supplies or not. Either way, a week and a half is not a long time, and I think it's important to get used to pumping and learn how it all works regardless of what pump you're on, and you aren't going to have any more success on a different pump, tube or no tube, until you work that all out. I went on the Medtronic pump at the same time as my dad, who had been type 1 for over 30 years and said he would only start pumping if one of his kids was diagnosed. I remember him having a lot of trouble at first, but now his control is much better than it ever was on injections and he can't even believe anyone wouldn't be using a pump.
Other than the tube, what problems are you having? Are you sure your basal rates are properly set up, and that your carb ratios, correction and sensitivity factors are accurate? It takes time to get these things right, and will be easier to figure out with a CGM. I studied for the bar exam too not too long ago, it might not be the best time in your life to be figuring all of this out, but then again you might have more free time than once you are a working lawyer!
Lastly, remember you are going to have high blood sugars if you disconnect for long periods of time, which is one area where the Omnipod has a big advantage for control. It's not good to be disconnected without basal insulin during sports, I usually lower my basal by about 40-60% instead of removing it. There is a leg pouch that Medtronic sells online that you can use for sports to protect and conceal the pump.
