it's easier to remove the front wheel and lock it together with the rear right at the seatstay bridge... Of course, it's impractical unless it's a QR.
Exactly.
So either you go with the QR and make things a huge pain in the ass for a little added security,
Or you go with locking skewers and sacrifice a tiny bit of security for the convenience of not having to remove your front wheel every time.
Either choice is viable, but frankly it's not worth the extra 500% lockup time to me. I'll stick with locking skewers.
...and it's entirely useless to say things like "If the thief is professional enough he'll just do this..."
Because if the thief is "professional enough" he can cut through your fugghedaboudit chain in a few minutes with an angle grinder anyway.
Everyone knows we're just talking deterrence here, and I'll say again what I said before:
A thief is not gonna waste his time ****ing with cone wrenches and specialized tools to get your front wheel out of a locking skewer, when there's a bike with QR's 10 feet away.
