I personally know 59 guys in rtp between Piedmont, psa, and envoy. About 42 of them have completed training and are on the line.
I can't attest to success other than having completed the initial training. There's an additional 5 guys that had started that dropped out. They were retired old timers that for the most part all said they didn't feel like jumping fields this late in life. I'm sure others have dropped or failed due to lack of effort and such.
