Raiding Again. When to drop 4p t7.5Follow

Hey all, I am coming off a raiding break and getting back into the swing of things. I always raid as arcane and will stay arcane even now, and certainly when 3.2.2 comes out. Right now I have 4p T7 with a few options to sway. One being badge gloves and the other being heigans robes. I am going to be doing some ulduar and some ToC coming up soon and was wondering when it is good to break the 4p T7 as arcane. I dont know that I get alot of benefit from it as it is but I am not sure. I have been swaping a few items around on the dummies to try to get an idea but it is not showing much. Any suggestions?

The second you get 2 T8 pieces. T7 was gimmicky but very mediocre overall. Yes, the 225 SP boost when using a gem is nice as is the boost but the recent nerf to that squashed it for me. If I ever get off my *** and farm on Mage again, going to get full T8 and live until T10 or T11.
