After much reviews,and much research on the proper way to lock your bike and the proper locks needed,I went with these...
A 4ft,12 mm steel cable,a brinks high security padlock and a 4X9,15 mm Kryptonite U-lock.
Here is a video also that explains a how to lock your bike,but after watching this video and many like it,I asked myself how the hell do I carry these locks with me when I am not in full commuting mode?(With my rack,rear bag,etc)So watch the video,and answer these questions about your own bike...
How do you lock your bike?
What kind of lock(s) do you use?
How do you transport these lock(s)?
What grade do you think your bike would have gotten?
