REFLECTOR: One or Two oil coolers?

[Velocity]

IO360-C1E6 with 10:1 pistons (from Lycon in Visilia CA - dynoed at 230 hp) -
173FG - 1 cooler in front - summer flying in AZ I watch my climb rate to
keep oil temps below max, but after level off oil temps drop to 200-215. In
winter (in AZ) oil temps 180-200.

What is your compression ratio?

Are all the high compression guys running two coolers?
