I also use the red n tacky but i personally i would have no hesitation with the blue grease either. Lucas really makes some great products that really work.
Personally I like the red stuff because it wont fling out if you lose a cap, it really stays put, i trailered over 150 miles with no rear seal and no cap with it once after i tossed a bearing and it made it all the way home with almost no lost grease.
