Your post is wrongly titled. You moved from light weight to RIGHT weight. (Right for you, that is.) I've also played the ultralight game, and backed off a bit.

Colin Fletcher had it right 40 years ago: Rule 1 - If you need it, take it. Rule 2 - try to take the lightest version that will still do the job you need it to do (Rule 2 is not a quote, but a paraphrase of the rest of that chapter.)
