That sounds like a good deal, but the question about the wing loading is better for your instructors and coaches where you jump. They may recommend renting a few more times at an intermediate size so that it’s a graceful downsize.
The reserve has to be at least the same size as the main, too, for it to be a good deal. There was a time when people would get smaller reserves (even something like a 135 with a 170), but you really don’t want to downsize on your first reserve ride. There’s a reason people don’t choose rigs like that any more.
In the longer run, that’s a good wing loading to aim for for many newer jumpers. Not all, though, which is why you want to talk to your instructors.
