Any particular rush? I personally would like to have for the most part all the same reels, the tried and true thing. Reel retrieve ration can be a bit over rated, caught far more fish with a slow to medium retrieve than a super fast one, I get get as fast as I will probably ever need with a reel in the 6 to 1 ratio, I have used a lot of baitcasters far slower than that.
Always an Abu Garcia man once I started buying my own reels in the 60`s, that changed in the later 70`s, some issues with some Abu reels, a better selection of left hand retrieve reels by the new kids in town (Shimano) gave me a mix. Might just be a personal choice but every bait caster I own is Abu or Shimano, I don`t know any one personally that has Quantum`s or any other brand used as much as mine were that are still happy with them.
I do have some dated reels, 70`s 80`s 90`s, no problems with them and even if I was still fishing as much as the old days no need to switch.
Buy one, try it out thoroughly and if you like it buy another, better than buying 2 different models or brands at once and having issues with one. If one gets old or breaks it leaves you with a parts reel, although most models tend to have the same problems with breakage or wear.
