Carvers or skinny skis?

I'm 52, learnt to ski 30 plus years ago on skinny skis. Didn't have the opportunity to ski for 25 years but now enjoying it again. When hired skis last year noticed skis were much fatter and curved in and out. Am looking to buy own skis, probably on ebay,as we drive to Alps. Should I go for the newer carver ones or doesn't it make much difference? I am a very pedestrian skier - love traversing red or blue runs - don't attempt anything flashy like mogul hills. Help please.
