What rear main seal?

I need to get a rear main seal for my engine. I need the 2-piece. I have read that I should use the blue one. I looked on Summit and there are 2 that are blue. Which one should I use? I see a blue in rubber and in silicone. There is also a very expensive one in fluoroelastomer.

Thanks for the advice. I want to make sure I get the best one. Don't want to have a leak.

Felpro Blue is all you need, local parts has them. If you are installing this with crank in block, rolling it in, be sure to use the little white plastic shoe horn, prevents from damaging the back side of the seal. Instructions in box.

Fluroelastomer is nascar stuff.
