Penn 320 GT2 Reels

I have two of these reels, bought when I lived in O'Fallon Illinois back in early 2000s to fish in Mississippi, however never got to good at tossing them without backlashing. I want to keep them just in case, if not how much would be a good asking price. If anyone has any suggestions on an easy way to cast these I'm all ears, my favorite two reels at the moment are my two Ambassador 7000C3s on MH Ugly Stick Tiger rods I hardly ever backlash these, they are the best cat reels ever.

i have the same reel i found with those i spool them with 30 lb big game and use around 3 0z of weight. tighten the spool tension all the way up then slightly back it off on the penns compared to abus i have to use alot more wieght and alot more thumb
