Why not 40# - have you seen them get line shy? BTW, still mad at you for getting COVID last September. I was really looking forward to meeting you.
No real reason other than I've never seen any need to go heavier than 25, and we always have plenty of 25 flouro onboard since that's what we use when fishing live bait. I'm not nice when fighting albacore and I don't recall 25 ever being a limiting factor.
When they're up and snappy then it doesn't matter if it's 25 or 60 really. When they're not, it likely doesn't make a big difference either way.
