What are your thoughts on changing to new versions of the T:Slim? My DD already has a T:Slim and has 2 1/2 years left in her 4 years. My son is getting ready to switch from OmniPod to T:Slim (we're in the medical necessity process now because he has only been on the OmniPod for 2 years.) Originally, my plan was to upgrade DD to the Dexcom integrated version. But, with it being G4 and with G5 now being out, it has much less appeal. And she's interested in the T:Flex, too, but I don't know if there will even be an upgrade option to go from the Slim to the Flex. And our Tandem rep said that a Flex/Dex combo isn't being planned so it's an either/or. If there's an upgrade option for the Flex, I guess we'll have to re-evaluate - and depending how old she is then the bulkier pump might lose it's appeal since girls' clothes aren't really designed for hiding things. Right now, she's 11 and uses about 100 units a day. So, since my son is switching now, we have three choices. T:Slim now. T:Flex soon. T:Slim with G4 later. When I talked to him about the options and dates, he picked the Slim because he can get it now and that's most important to him. I'm tempted to wait until the Flex is out because he was so excited about that one. He's used to carrying a PDM around so the Flex size probably won't matter, and everything he wears is baggy and has pockets so it's not a concern. This is the pump he'll use for ages 13-17 and he's around 100 units a day. I just can't decide! Has anyone else considered the Flex? Is anyone planning to switch to the one integrated with the G4? I'd love to hear what you guys think about the options and why you are planning to use the version you are planning to use just to see what points I might not be considering yet. Thanks!
