SASless. The UK H19s(Whirlwind) were fitted with nose wheel lock pins(either in or out) as the majority were for ship use. Initially we did EOLs with the pins out and as you say there was a lot of wheel shimmy. So eventually we flew with the nose wheels locked unless ground taxiing. The EOLs were now much nicer and became really nice in the gas turbine(Mk 9 & 10) when the RRPM were raised to 220 rpm. Almost as easy as the Wessex!
