Hard to go wrong with the standard if you only get one. It does pretty well in lower winds. The UL goes up with a couple mph less, but has a smaller range, so you would be reaching for another kite more often. If you are looking to learn tricks, I wouldn’t get the vented. When the wind is up, that makes tricks harder. The vents slow the kite down, but you still need to maintain slack. When you are a little more experienced the vent would be great for higher wind days, but those are they days you do fewer tricks not learn new ones.
