doogie:
can you stretch your bridge, im curious to see anyone who has one if its possible
You can, but I wouln't recommend doing it. I did it b/c I was 17, stupid, and bored. I originally had a 16g. I bought a 2 inch long 10g taper and slowly worked that through being really careful not to tear anything. I had that in for about 3 weeks before deciding that I didn't want it because of the high risk of it and taking it to a 14g and eventually just letting it heal.
EDIT: I wouldn't recommend it unless you're absolutely set on it. If you like it the way it is, keep it the way it is. Don't risk ruining it.
