I think that he just meant that they are certainly not "way to big" for you...unless your like 4'8" or something.
For instance, I'm 6' tall and a shop would size me with a 50" pole, so technically that is my correct size. I would consider something like 60" "way to big" for me. I prefer something around 46" which is technically on the small side even though most people on NS would consider them normalish.
I also think that 39" is pretty much useless, but that's just me...then again I don't ski much park.
