Mike, check my edited post. I looked the Motul figures up and edited the post 4 min after the original post. But I was too slow as some had already quoted it.

I thought they were pretty similar but as my edited post says it differs about 60 degrees at the wet point. Im not saying its the best but its good value for money. A lot of track day ppl use it over here with good results.

I guess it all comes down to how much and hard you track your car. I only go a couple of times a year so for me SRF feels like a waste of money. If I got as much Ring Action as you (God forbid ) im shure I would use SRF too.
