Stradic or Sustain?

[Fungus]

I am in the market for a new spinning reel. I am seriously considering going with a shimano as my past experience with some of their products has been positive.

My main question is; is the Sustain really worth the extra cost over a Stradic (or 2)? I am specifically looking at the 8000 size.

I have done several searches and did not find the answer to the question, so I figured I would ask.

Thanks for any and all opinions.
