Re: What head would you run on a SC 615?
Wayne, thank you for the info. I bought an SR20 598 this week that I will freshen and put in this fall after I get the season over. I don’t want to start over with a new combo at the middle of the year. I thought about the 12 degree stuff and it might run slightly better I couldn’t warrant the extra cost for the little bit of power over the 20* stuff.
Everyone I know with the 20* head likes it and they make good power.
