You will be replacing rings more often with 1 ring design. In my opinion, it's not worth the extra horsepower. When I say extra, I mean very little. But, if you are in a situation where you are racing and every little bit counts, it may be worth it to you.

you might see a little more oil consumption with the single compression ring pistons but i have always put 40+ hrs on my pistons without any issues or smoke, they could have gone longer but i replace my pistons every season
