Is it bad practice to store skis and have them strapped together? A single rubber strap in the center of the ski compressing them together gently? Assuming it's stored upright, with storage wax, in a temperature controlled environment, will this damage or degrade a ski, does it make any meaningful difference? Sorry in advance if this is a stupid question.

Edit: the reason I ask is because I have a lot of skis, and I don't have a fancy alter/room to hang them all up - it's much easier to keep them strapped together because they all have to go into a closet for the off season. Not strapping them just make things way more unwieldily.
