Nothing wrong with 100% pils. Some say to use a couple of maltsters to get some complexity.
35 to 38 IBU is good. If you want crisp and dry, use the water for pils on braukaiser.com, Ca=59 , SO4=89 , Cl=63 from memory, so check it, and no alkalinity so I build from RO.
I do like to use late hoping for my Pilsners. A fair amount at 30, 15, 10. Tettnanger is very good in these, and so is Saaz.
If you want clean 940 is the way to go.
