Returning after being away for 5 1/2 years!!

Hello to all my fellow truckers out there! I'm making a return to trucking after being out for 5 1/2 years. I've taken a course to renew my CDL and I'm working on getting my Hazmat in the near future. From what I was told, I'm starting out as a newbie because I've been away from the game so long. However when I took the CDL course to renew my CDL, I was the best student because of my driving skills. I did pretty good for someone being away for so long. But my question is that I've been looking at two companies to go with, Transport America and Roehl. Does anyone drive for either company? How long is there training with a trainer? I'm not to happy on going out on the road with someone for 4-6 weeks because I feel I don't need to be out that long with them. I want to earn my own miles on my own. This would help in my decision listening to your comments. Thank you again Truckers!
