With the PPL its different things to different people.
Some find the handling a breeze but struggle on RT and NAV.
But for most the PPL disappears into memory when they start doing more advanced courses. The work load in the CPL and IR is heavier but its different things to what you had previously. The fact that your max point has now increased since you went solo means you are proberly still working as hard as on your PPL but with a great work load. Imagine what it would have been like if you had gone straight from solo to twin IR. Which is why I am waiting to see what the new co-pilot license students out come is going to be.
