An item racers never seem to have enough of is extra glue needles. The RM2 needles are plastic tipped so the length can be trimmed for a fresh surface and to minimize clogging. Typically, one needle will last several weekends or more. The thin bore tip is best used with very thin glue (#2043T). Stock up on glue needles from RM2 so you never get caught in a pinch during a long race outing.
