I know several people who have chosen to go with a vbac which has worked out well. I realize that's not very good evidence, but I think the figures quoted are that the chance of scar rupture/dehiscence are less than 1%, and since you've only had one cs it's probably fine for you to try for a vb
. As long as you're in a hospital and there's monitoring on you things should be safe...and if you're really unlucky and have to have a cs well hey, at least you tried.
My personal opinion is to try for a vbac if you want to, you've only had one cs and that was a low cs (i.e. not a 'classical cs' vertical cut)
Hope that helps.
