Ret leveling weapon progression

Hey everyone! I’ve been leveling fairly steadily as a ret paladin. First time experiencing the horde side of things and I love it. Weapons seem to be the number one power increase and I’ve been eyeing ice barbed spear as I approach 51. Is this the best upgrade I should be aiming for? It seems like I’ll realistically use it until 60.

I got ravager from SM but didn’t get any of the drops from Uldaman. I am 45 now and using the level 43 BoE spear, Bonechewer I think.

Any suggestions?
