I am looking at lasers for my son coming out of optis. Does an older (1986) laser have the same deck layout for hardware as newer versions? Will the hull be competitive if in good condition. Did they weigh the same back then? If I find a clean, dry, stiff older hull what would be different versus a newer model? My son was very successful in the opti class, so I would like to get him a raceable hull, should I avoid anything in particular while shopping? Thank you for any advice you can provide.
