I would leave the forelock. There's a boarder at my barn who roaches her Arabs mane, and last time she did it, she decided to do the forelock too. Poor horse looks pathetic. Of course she's fat, and the roached mane just makes her look fatter. But the owner doesn't have time to come out during the week, so she says its easier to roach the mane instead of trying to keep it nice, as its pretty thick I guess. Your horse looks good with a roached mane. For a few years the only horses I'd seen with roached manes were the polo ponies, and I always thought they looked a bit weird, but I'm starting to like certain horses with roached manes. She's a pretty girl.
