Skiing FIS Race skis on various types of terrain (moguls, groomed blue, groomed black)

Ive recently been skiing more on FIS style race skis. These skis have a stiffer feel and a more solid type of construction when made. I have been testing which length in the GS ski to use as an everyday long radius ski based on how well it can ski both moguls and groomed terrain. The longer 188cm 30m radius ski felt best at either full speed or skiing the bumps. Not much in between. The 178cm 23m radius felt great at almost everything but I liked the longer length in the moguls. Ive gone for the 183cm 25m
