So I rode GL yesterday and let me say that I highly underestimated this ride. Had 2 rides on it, balanced (4 riders) and un-balanced (3 riders). Let me just say OMFG the unbalanced ride made my eyes water. The park does do a good job trying to make sure it's balanced unfortunately
Rode twice and waited about 60minutes each time.
Robb you were correct, you will get completely different ride experiences depending on weight distribution.
