Best figures from the SITH line?
Easily before I begin the EVOLUTION packs (of which Hasbro are not continuing) were the absolute best. After acquiring all of them (the troopers in triplicate) I'd have to say that if you didn't get the EVOLUTIONS Anakin then you lost out---big time. None of the SITH Anakins (without major tweaking) even held a candle to this one. But on to the actual line:
1) #56 Obi-Wan Kenobi (Red Leader Pilot)- horrific cloak (glad they made the cloth fix in the Saga version) but undoubtedly the best figure Hasbro has produced. PERIOD. End sentence.
2) #41 Clone Trooper- If the later Tactical Ops Trooper (#65) had been based around this sculpt rather than the AT-TE Gunner (#38) then it would be hands down a possible number one. I'd even have done without the removable helmet. The #41 is super poseable... and that counts when you buy ten+ of them for recreating scenes.
3) #6 Clone Trooper (Red variant)- Nuff said.
4) #13 Count Dooku- Almost as good as the EVOLUTIONS version. Completely made up for the unposeable AOTC version.
Honourable mention:
-The head sculpt in both #14 Chancellor Palpatine and #35 Palpatine. Deadly acurate (too bad the figures had no movement--- if the #14 cloak were cloth..... then we'd have something)

-Take the hooded cloak from #50 Anakin on Mustafar and put it on #28 Anakin (with Sith eyes), place that hybrid figure in front of your row of 8+ #65 Tactical Ops Troopers. Enjoy.
-I've never found a good Mace Windu figure. Ever. #10 is no exception to that rule.
-#22 Kit Fisto makes up for the AOTC horrific pose and face. Wish all Jedi (make that figures) were created for such poseability.
-In closing, I could have done with actual new figures in the line instead of a constant repaint job (#66 & #67 holographic repaints, #61 & #62 repaints from earlier lines...etc) but as I have every figure (#1 through to #68) and most of the variants/exculsives hanging on my office wall (with others opened and posed) then I can't really complain. Glad I chose this (out of the three prequel movies) movie to be the one that I'd collect the entire line.
-Oh yeah, only the Deluxe Grievous was OK. #9 looks great with arms extended but on the whole Hasbro has no idea (just look at their 12" version) how to present this guy. Here's hoping SIDESHOW takes a crack at him later.
