it's really personal preference. i just read that other thread and it's a trade off between potentially getting more action and potentially losing more fish in my opinion. if you hate losing fish or would be pissed if you lost a big one b/c you went light, then go heavy. if you're confident you can take your time a play a fish on light line and don't mind potentially losing some go light.
personally i've lost enough big ones from going too light so i tend to go on the heavier side. there was even a period when i was only using light steel on bass/pick ponds. even if i had a monster on i never worried about losing a fish due to line failure.
you can catch big fish on both. tafts and i caught tons of big pike all day on 50# mono leads but the biggest of the day came on a steel lead. you never know.
