the thing is, like any muscle group, you cant just do high reps. you have to be moving high weight too.

you cant spend all day doing curls of a tuna can and expect to get big arms.

you have to build the strength to move good weight before you can start doing higher reps for growth. theres no guys in any gym with >18" arms not on dat der celltech curling 15lbs at high reps. they are all curling good numbers at high reps.
