CPL wouldn't help on that situation I think... to be honest on all my photos I almost never used a CPL

I know lot's of landscape photogs love to use CPL. 3 stop ND is a good start for sure though
more practice 
yup more practice for me.
and save up for the GND and CPL. or better yet, i'll sell the 3 stop and buy a 9 stop ND.
