Got a Krytonite new york u-lock as a gift. It's brightly colored yellow and easily recognizable. Thought crossed my mind if obscuring the brand by taping it up be more beneficial?

Leaving it as-is would scream to thieves:
"I'm that yellow u-lock that is tough to break unless you got a the time to grind/torch me off. Better off picking some other bike."

At the same time it also screams:
"Hey, expensive lock here which means bike is worth a ton to steal. Well worth the time!"
