I know what you mean Pulse - it's just that ATC usually shove an A.321 in front of me and then remind me of the vortex spacing.......then tell me to hurry up or I'll be number three to a 757

(Ended up doing 155kts to two and a half DME)
Flying a bit at a smaller place in the interim and getting used to following a Tomahawk when I'm trying to stay in the circuit and get the speed back is different........mind you ATC suggested he keep his circuit tighter in future, but if the guy was a low time PPL or student I'm happy to pace myself.
Tell you about another one that got my back up next week......
