the spicer 508-x, which i stock, is the best cheap joint you can install, it has a forged cross no zerk fitting to strengthen the body. If your not putting in chromoly outers your stub is probably going to break before the spicer joint does, they hold up well even with chromoly outers.
If you want more strength and can afford it, Bobby super joints are the way to go. they are priced right first of all, second of all they are arguably the strongest.
If CTM's are stronger it does not matter b/c whatever shaft you put around them is going to break first. so you might as well buy the cheaper ones.
And ill beat said pirate vendor on the yukon joint.....
