Replying to Need new ski bag i swear

I've had the dakine fall line 190cm for about two years now and used it on trips to europe consistently. However, this bag is profoundly terrible. My skis are 178cm which leaves 22cm of slack in the bag. Even filling this gap with my outerwear, the bag sags so badly on the ground that the wheels dont even see use. Dragging this 6'5" 60lb body bag around crowded train stations is a fucking nightmare.

Anyone know a roller bag that doesn't sag on the ground like a waterlogged paper towel tube? Maybe has a carbonfiber skeleton to hold its shape when its lifted 0.002 inches off the ground?
Considering just getting a carry bag but I dont want chronic muscular imbalance from carrying my entire ski setup on my right shoulder ;)
any suggestions are appreciated
