Replying to How to transport skis

I've got a ski bag from the 80's that only fits 1 pair of skis. Im trying to work out how not to pay 100+ for a 2 ski bag. I usually go to a resort where i own a place so a ski bag is never necessary, but this time im taking a bus. I have 3 pairs of skis 2 with bindings, my problem is that in my old bag i can fit 1 pair of twins and my unmounted moguls skis, but i have another pair of twins that im taking to get remounted for tele.
Any suggestions on what to use for a ski bag? im not cutting up a surfboard bag though to suit though.
