Pool design

Hello all, I am new to the forum, and I am trying to get a little feedback. We are currently in the process of getting a fiberglass pool installed with a fiberglass tanning ledge. The pool is a Freeform 14x32 9000 gallon pool and the tanning ledge is 18x9 10 inches deep. We are also doing a Pentair automation system. The way it is being set up is with one skimmer in the main pool and one skimmer in the tanning ledge. The main pool has six returns, (2 deep, 4 shallow). We have 2 Pentair VSF variable speed pumps and a filter for each. Is this the best way to set this up? I feel like one of the pumps will be over worked while the other is barely used. There will also be two coping waterfalls. Coming off of the pool. Any feedback would be greatly appreciated! Thank you
