popa-
The reason I did my private multi first is because I am doing it under VA part 141 so the duchess is approved for all of the ratings. I am doing all but my CSEL in the twin while 60% of it is paid by the VA to avoid potentially having to buy a block of it down the road and having 100% of it come out of pocket.
When I finish my ratings I am going to stay on as an instructor at my FBO and hopefully get enough multi hours to stay proficient and have a recency of experience. For me personally It is worth the money and I dont run a chance of having to pay the big bucks for safety pilot time down the road.
