For what it is worth. I use nothing except standard tension oil rings in everything. I have never had problems with getting horsepower. My last light tension racing ring was way back in 1980. All my engines before that had some oil control and blow-by issues. Since then notta. I will gladly sacrifice a little hp for better oil ring seal.
By the way. Do always check all of your rings including the oil ring rails for ring gap. I have had to file them from time to time.
