I get splits, but they are rarely actually on my ends, so I don't worry about trimming them. *shrug* I would have to shave bald to truly get rid of them all, and it's really not that crucial.
Once it gets long enough for me to be able to actually 'see' the ends, I'll start doing search & destroys to snip off the splits that actually show up at the ends.
Otherwise, I leave my hair in protective styles, keep it well moisturized, and leave it be.
