Bike lock advise and recommendation

Hi everyone,

I am wondering if anyone can give me any advise or recommendation if my
current lock system is more than adequate to secure my bike outdoors.

In my last job, I was fortunate enough to have a secure indoor bike
parking facility. To lock it to the supplied bike post by my
ex-company, I used a combination of a short Kryptonite Evo-Lite U-Lock
(using Sheldon Brown's locking technique) to secure the frame and rear
wheel and a MEC thick twisted braided cable lock to secure the front
wheel to the frame. It had kept the bike from being stolen for years.
The same combination is used for my daily errands -- shopping and
visiting friends. -- and not usually away from my bike for more than
2-4 hours.
In the new year, I may be working with a new company and they do not
have any secure parking for bikes and do not allow bikes inside. So, I
now have to park my bike outside for close to 8 hrs. I will be working
in a high bike theft area of the city and people told me that my
Evo-lite U-lock & cable lock combination might not be enough. They
suggested something like a Master Lock Street Cuff, Krytonite NY Lock
and another U-Lock that as a top dog emblem on it which I can't
remember. Some even suggested to me using square link chains and a
U-Lock combination. Those sounded pretty drastic..
Do I need all that? Mine is a touring bike that is used for both
touring and commuting.

I am fully aware that if people want to steal my bike, they will think
of a way to get it. I just wonder if my current U-Lock is up to the
task or should I get a better and stronger one?

Thanks..

David.
