There's a lot of information out there that cautions against having different brands of tires on the front and rear so be careful with replacing only the front with a different brand. The following quote is from an article by the National Highway and Safety Administration:
"Make sure you get a matching set of front and rear tires. Unlike car tires, you need to make sure that your motorcycle tires are a �matched� set. At a minimum, they should have complementary tread patterns, should both be either radial or bias ply, and ideally be the same make and model."
