I already bought one bag and already have 1000 of each saved so looking for other ideas besides saving for champ bags at 50 cause that is already in the "bag."

So looking for some advice on what else I can spend my PVP commendations on. I am currently lvl 43 and I have 1000 of each. I have already bought every lvl 40 piece of PVP armor and the level 42 light saber. I am a sorcerer. I don't want to stop PVPing until I get to 50 but I also don't want to earn a bunch of comms that are going to waste.... What can I be purchasing while I make my way up to 50? I know I will want to be maxed when I get to 50 for the bags but I already maxed at 43. Any help would be appreciated.
