Thread: What line should I finish grinding next?

Okay, so I'm almost ready to buy the T110E5 (another 3.59 mil creds). I was wondering what line I should grind next. I'm going for these tanks:

AMX 50 B (at the BDR)
T57 Heavy (at the T69)
Bat Chat (at the AMX 13 90)
M48A1 Patton (20k xp away from the Pershing)
JagdPz E-100 (at the Stug)
Object 263 (at the SU-100)
Object 268 (at the SU-152)
T110E3 (almost to the T28 Proto, which I can get the T28 from and continue from there)
T110E4 (again, almost to the Proto)
M53/M55 (at the M40/M43)

I want something that will be useful for Clan Wars, but fun at the same time. I'll probably free xp my way to the AMX 50 100 to make the grind easier. I have to rebuy the 13 90 because it was a pain in the butt to grind.

Also:
Object 140/T-62A (at the T-34)
121 (at the Type T-34)
