Not to tell you what to do, but i think those reels are a little undergun for those class lines. The 5000's are good for 20-30-40lb, 6000's for 30-40-50lbs, the 8000's are more geared towards 50lb and 65lb, I would suggest getting a broader spectrum of sizes, before buying duplicate reels. The 10000, 18000, or 20000 are more suited for 80lb/PE8 lines. The capacity will be too small on a 8000 for PE8. Just a thought.
