Gear changing and braking help

I'm a newish driver (had my HR for bit over a year).

In regards to a road ranger (non synchro) transmission, I'm curious what other drivers do when they need to change down gears and brake at the same time, for exmaple when a traffic light turns red on approach?

I'm comfortable changing gears but if I need to brake aswell i'm a bit lost, I usually just foot brake and run the engine brake down to just above idle rpm then clutch in and continue braking to stop.

I've seen videos of 'jamaican truckers' using a heel-toe method but it seems a little rough on the gears,

I've also considered left foot braking and rev matching with the right foot.

Anyway I'm just looking to brain storm at the moment so if anyone has ideas or advise please comment.

 

So do you just brake with your left foot and use your right foot on the throttle to float down through the gears?
