I have a Mic-Keyfeeding tube and it doesn't bother me. Occasionally i'll get frustrated cause I can't wear really tight tops but that's it. The great thing is that anything can go through the tube. If you have to take any gross meds most of them can got through it and it's good for certain medical tests. And don't give up hockey, if your worried about getting hit in the stomach area it actually doesn't hurt. And I have the same issue with weight as you do, I don't always use the feeding pump though I only use it when i'm sick or my weight is low.
