vbac advice or stories please!

.
Really feeling want to try for a vbac this time around. I had a c-section with my first child almost 3 years ago. Nervous because the two doctors in my OB practice have differing oppions. The high risk Doctor said he sees no problem with trying while the other Doctor is saying 70% chance I'll need another one and wants to schedule c-section at 39 weeks. Really want to reduce recovery time and have a vaginal birth.
