Tape is out. Like I said, this is even more difficult than a standard pump inset because I'm trying to keep a CGMS site in as well-and it is not nearly as flush against the skin as pump sites are.
I don't see why some tight-fitting solution that takes the place of underwear like Speedo/Nike/Underarmor won't work. I am hoping that is my solution. I probably won't know for sure, however, for a while, because in March you can bet I'll be in a wetsuit, which will effectively serve the same purpose as those other solutions.
So people know exactly what I'm talking about, here's a picture of a CGMS site http://drea-girlonthego.blogspot.com/2007/03/minimeds-new-minilink-transmitter.html
The CGMS thing that I'm worried about is the cream colored mushroom shaped device on the right. It is about 1" in diameter, and does not have anything tacky on it that sticks it to your skin--it is held down by tape, and is thus very susceptible to 'catching' on things and getting yanked up and out. OUCH.
I just got my pump less than a week ago. I will not ride with mine...there's no way I'm going to ride with an $8000 device when I'm falling hard enough to get a concussion. Additionally, leaving the pump connected exponentially raises the risk of the site being ripped out, because if the pump comes loose even in a minor fall you can bet it will raise the chances of ripping the site out with it. Seems like it would only be a matter of time before the pump would come off during a hard/awkward fall.
