orvis waders are just not worth it. You might get one season out of a $250 pair of waders but you'll have to replace them next season. After two seasons you spent what it would cost for a pair of G4's. I have freinds that have had a pair of simms for 10 years and they still use them as a backup to their new ones. It's worth it to get the simms, buy the best it can only hurt you once
Another point to make is that I fish very hard in the spring,summer, and fall so I put a lot of wear on my gear. So factor that into your decision because not every body fishes from 6a.m. to 9:30 p.m. 5 days a week.
