Pump user here too, been on mine for 5yrs now and has revolutionized my life, just stick mine in the pocket of my baggies when on the mtb or just in my trouser/jeans pocket. In 5 years have never pulled a canula out by catching the tubing and have only caught the tubing a handful of times. They are tough little bits of kit as mine has stood up to several bad offs that have resulted in several broken ribs 😳
My email is in my profile and am happy to answer any questions if anyone wants to ask about life on a pump.
Please post a link to your blog as very interested to see how things go.
Good luck with it but as said above, some people dont get on with it just be prepared to put quite a lot of effort in and the rewards will more than justify it. Good idea to write down as much as possible when it comes to exercise, I have found some quite strange things needed with basal rates pre, during and post exercise including overnight and the following day.
