I've got the spline lugz on mine. I also got the matching locks to go with the set. The way I looked at it is the extra cost of the splines is like having two different sets of locks keeping my investment on my car. Should be a lot harder for someone to try and swipe my wheels. As for the wheel studs, if you can live with the different sizes, leave it as is. I know with me, it would bug me and I'd want to have them all the same size. But that's just me and in some cases I can be too much of a perfectionist.
