luggage advice -- traditional or duffle

<p>Thanks, 2boysima. I searched LLBean site again and found X-large adventure bag.[Rolling</a> Adventure Duffle, Extra-Large: Duffle Bags at L.L.Bean](<a href=“Rolling Adventure Duffle, Extra-Large | Duffle Bags at L.L.Bean”>Rolling Adventure Duffle, Extra-Large | Duffle Bags at L.L.Bean)… S already has one wheelie and I was trying to free up his hands. One of the reviewers on the adventure bag site claims that the bag itself is very light which is a major selling point for me. Has anybody used it before?</p>
