I would go with the new one. By the time you transfer warranty it's only 50 bucks difference. The only other way to resolve your dilemma would be to cast both rods at about the same time to see which one you like better. However I also think that if you own 6wt you should look at either 4wt or 3 wt: to my there is not enough difference between 6wt and 5wt. I am StC addict and own quite a few. For fly fishing I have 7wt Avid and 5wt Legend Elite. These two cover all of my fly fishing needs - so far...
