That’s the one I recommend for everybody, now…

Sufficiently long, sufficiently secure, & manageable.

If that’s too heavy, do check the weight & make a mock of that weight, to try on you while riding, then get the next-lower-security equivalent from Kryptonite, with the integrated chain, which is the same length ( if they have one ).

Ride forever, eh?
