Tandem t:slim X2 + Dexcom G5 versus Medtronic 670G

Newly diagnosed T1 diabetic. Which one should I get? Both are of no cost to me.

Is Medtronic likely to release a new pump within the next 4 years?

How likely is Tandem to release updates to the X2 that (1) allow it to receive CGM data from the G5 and (2) add the automated basal delivery algorithm?

Will the G6 require no fingerstick calibrations?

How often do people get occlusion alarms with the t:slim X2?

How is the Enlite 3 sensor? Does anyone know its MARD?

The 670G pump seems quite bulky to me (it is over twice(!) the volume of the t:slim).

EDIT: I spoke with Tandem rep:

  • G5 communication update likely Jan/Feb 2018
  • Hybrid closed loop algorithm likely Q3 2018
