It's quite interesting. I've got a biggish scope on a smallish mount, on my balcony that is shielded by the house from one direction. Depending where the scope is pointed, wind gusts can create wild movement in Dec, or in RA, or not at all. It really is like a sail. You can tack your scope into quite a strong headwind with little problem, but try a broad reach and it wobbles all over the shop :-)
