Anyone cryo-treated anything?

[Jeff240sx]

At 300 Degrees Below Orlando, they cryo-treat pistons and tranny gears.  They claim it is better than forging things, and the life of the part goes up by 300%
I wanted to know if anyone has useful info about cryo-treating anything.
When I get my SR in, since people say the 6-speed gears are weak, I was gonna have them cryo-treated if it was worth it.

Mark West has said that his pistons were cryogeniccaly treated by the former owner.  

I think this is a reasonable way to gain some strength from a part.

Check out www.diversifiedcryogenics.com  $8/piston sounds good to me!
