YFZ High compression piston

I was wondering if anybody has installed a high compression piston on there YFZ or if anybody has any info on them. The only one i have seen is from GYTR.

Im thinking about installing one of these on mine but just wanted to make sure i was making the right choice on which to get.

YFZ High compression piston

Couple guys on other forums reported having problems with the GYT-R pistons(JE). Some thought there might have been a bad batch of them...but there is about twice as many people that said they liked their GYT-R piston.
