if I played a links course maybe the difference would be marginal, but parkland, winter vs summer is night & day
In Scotland most courses are being protected due to lack of any growth and damage from frost as demonstrated by Clive the other day.
our place is much easier in winter at almost 600 yards shorter along with the greens being very receptive. only hole that isn't is our 7th with in summer is a 500 yards par 5 off the whites, which is played into the prevailing wind (a westerly) for some reason we play it 12 yards further forward as a par 4!!!!
