I have both of the rods you are interested in. My ZXL 590-4 has been fished twice and is in almost new condition. My 6 wt. ZXL isn't for sale though, as my brother gave it to me as a father's day gift a few years ago. If you're looking to possibly trade, I'm interested in a high end (Sage or Scott) 6 weight with a fighting butt. I'm heavy on 5 weights (I own 6 of em, all Sages, except for one Redington CPS 590-4), so I may be interested in unloading the ZXL 590-4.
