Perhaps an over-asked question, but I've never seen one of the LW "Executive" roller bag. It swaps the traditional aluminum frame of the "Stealth" model for an ABS plastic frame It is 2.5 lbs. lighter, but other specs are identical. Wondering if the ABS is robust? The weight savings, bend resistance and somewhat lower price are considerations. From owrking with tons of ABS pipe, it's pretty sturdy when it's young (like me), but can get brittle with age. Not an issue with aluminum, but it's virtually certain it will get bent sometime that I'm forced to check my bag. Looking for real-world experience. Thanks!
