Skiing on "hot rentals" is a little difficult, depending on where you are going to ski. Some centers, like ours, feature great skiis for rent and they are about $50 for the day. Most centers, though, just rent side cuts that are already 2 years old and most renters don't really know the difference.
I would rent some very hot skiis for a day or the weekend and then go out and do some research...just like we do here on sbonline when we wanted to rent a villa for our upcoming wedding this November on our first St Bart's visit.
I was skiing on 175 Volkl 6Stars, but they will kill you. Now I'm on 182 All Stars, which are even tougher, but your husband might get away with the 4 Star and be able to work it with his height and weight. I am 6'2" and weigh 145, and even at 55 years young, I still get paid to Patrol 5 days a week, schlepping a 60 pound tobogan behind me...and often another 250 pounder inside.
Do your research and carefully read the Ski Magazines that are featauring the new skiis and boots this time of year.
Skiing on 15+ year old equipment is dangerous and really stupid. Sorry, but we are so busy patrolling that when we see people with such old stuff, we STRONGLY suggest they go into the cafeteria for a hot chocolate...and stay there. Your skiis are finished -- the camber is gone and your boots cannot support your feet, ankles, nor legs. Do yourself a favour...if you like skiing at all, throw your old stuff out right now!
