what is the best oil and filter for 01 750 gsxr

I always ran ams oil in all of my ninjas. and know that I have grown up and smeeled the coffee, I have my 2001 750 gsxr,and love it. (way better than any ninja) but I was wanting to see what kind of oil and filter everybody else is running?

Please use the search function, and look in the oil & lubrication section. There are many answered questions on this subject already, thanks.
