I have been thinking of putting PowerPro on my Two Abu 7000ic3's and my two Penn 209's and I have a few Questions. 1. I was told not to get bigger than 65 lb line, why? 2. What pound line should I get? 3. How much backing should I put on the reels? 4. What pound backing should I get? 5. How much different will the reels cast with braid then the 25 lb mono I have now? 6. I was told to get the 150 yard spool, Should I get it or the 300 yard spool? Thank you for your help.
