I'll concede that long downhill routes can benefit from engine braking; I was more responding to general use of downshifting/engine braking when coming to a stop.

Shifting/rev-matching without the clutch can present its own problems (grinding the synchros). If you've gone this long without trouble, consider yourself lucky, but I don't think it's a recommended practice.

Still, would you catch a break if your engine breaks while you're engine braking?

I heel-and-toe every day, but never for extended periods.

I mean manually shifting using either the paddle shifters or the transmission selector lever.
