Still need helping finding right 135mm

Ok after getting the 135 2.8 nikkor, I am still on the look out for the right 135mm lens.

I also have an ancient rokkor-x that is 135mm 3.5. I like the fact that that lens is very tiny and lightweight. However, I have a really bad copy. I might go ahead and purchase the same lens because I like the feel of it.

Are there any other 135mm lenses that are f2.8 or 3.5 that are lightweight and small?

I just bought a nikkor 135 2.8 Q non aid and it's very big and heavy and just not comfortable for me to take around with me. The rokkor at least didn't take up much space in my camera bag.
