With the PC it's easier to get a smooth and level surface. The JJ

work required to use the PC, I'd probably give the JJ a go. It will be
a lot easier to maneuver on the upper courses. After you've got
everything solid, spread a little extra sharp sand on top and screed
it with a long 2by to fill in any low spots. Regardless of which way
you go, wet down the material before you compact it. Provides a
little lubricant so the material compacts better.

Thanks. I will look for some extra sharp sand try to post a follow up.
Will wet the material too!

I worded that poorly. I meant spread some extra sand and use sharp
sand (mason's sand, not play sand). Generally you want 1/2 an inch to
an inch of sand on top of the base material. It's a lot easier to get
the block positioned even and level with a little sand on top of the
compacted base.

Good luck,
