G'day Mate,
Here's a video I made of a 1hr circuit session in a PA28-181 a few years back - pre-PPL days.
YouTube - Circuits Benny Hill style - Bankstown YSBK You'll see in the video climbs at both Vx and Vy as I tried to keep a safe distance from a C150 ahead of me.
This particular Archer was a bit of a monster though, 75kts and 900fpm roc with 2pob and full tanks.
Don't mind the music - I thought it gives the viewer a good idea of what it's like in the circuit
cheerio
