Another good thread.
Alot has been said on this subject, but each year we see improved MONOs and improved BRAIDS so opinions change.
for me, it really depends on a case-by-case basis.
Boats- I prefer braid.
Light tackle - I prefer braid
Sandy beaches- braid
Rocky areas (Block Island, Beavertail, Cutty,etc.)- MONO

convention reels (ABUS)- MONO on all
My VS 150- I tend to lean towards braid due to the size of the spool, but prefer 20lb backcounty...so I'm experimenting with both.
Big fish Generally-MONO !!! (I have more confidence in my knots and abbrassion resistance)
