In the piston twin I have spent the most time in, (MTOW at ISA/MSL) Vy is 105knots and Vyse is 96 knots. That gives a 9 knot sh!t fark factor. Hence my adhering to the speeds above.
I have not had the wide exposure to different types that you have, and as such I am curious to know if other types have the same ratio.
I still prefer to peg Vy and get up sooner. That 100-200 feet extra height (over a cruise climb) when the engine quits approaching circuit altitude/LSALT may just make life easier. I would also be flying the circular departure path you so eruditely suggest.
