Thank you all for your input.
I must admit that it scares me less to have to demonstrate a few maneuvers (PPL, 1.5hr checkride), than an actual IFR checkride
(ATP 2-2.5hr checkride) in an airplane I haven't flown in 15 years. I also think that it might require more training. I am trying to do this as cheaply as possible. I have the airline pilot syndrome, even though I click the automation on a regular basis, I admit I don't do it for a holding pattern
I think I will go for an hour as a test drive and see how rusty everything is.
