Just as a general rule of thumb, mecanum drives are crap when it comes to being able to grip and just exceeds in slipping on surfaces. Honestly, the only advantage mecanums have to other drive trains is the strafing ability and mobility but is bad when it comes to speed and being able to push other robots. Other drive trains that are available are direct drive or the 6 wheel drop. But its up to you on what to use.
