You mean when we're out on the bay and I'm catching 80+lb blacks and trophy reds.....I think it really depends on what your fishing for. For the most part I use the rolled up crappy memory holding spools. I make allot of tog rigs outta 40lb. and use 40- 60 for chunking for stripers. For trout and lure fishing you can't beat the flurocarbon. But tomarrow when I'm out fishing the Ches bay for 80lb+ blacks and hopefully some trophy reds mixed in I will be using the leader that comes in the 100yard increments with little memory. I hate to loose fish and think its easier to handle vs a slinky and keeps your line from getting tangled since its pre-straightened.
