Checkboard has it, Especially when you obviously intend on knocking it down fast. Not to belittle any of the Grade 3s but they will slow you down because of their own limitations.
As for aircraft, yes shinny new aircraft are nice but only if money is no object. You gain nothing from paying more to fly newer aircraft. When it comes to private flying I fly the cheapest aircraft I can get. Why waste money on crap inside when I want to be looking outside.
