Upcoming Tournament

So, come February I'll be heading to the Vapnartak 40k tournament and it's time to finalise what I'm aiming for list wise.....and even army wise!

I'm currently torn, I have 3 options in regards to Army with various pros and cons to each choice - one of y main considerations is that I really don't want to be buying anything else as I already have a massive amount of unpainted figures kicking about. The tournament is a one day affair and you play four 1000 point matches throughout the day. I attended last year and found it was one of the more fun and relaxed tournaments that I've participated in. My choices boil down as follows:

Eldar
Pro: I have LOTS of eldar figures so I can pretty much field any build I can come up with.
Con: I have LOTS of UNPAINTED eldar figures, if I decided to run with the Space Elves then I'll have a pretty sizeable task ahead of me getting the army up to scratch.
Con: Dated codex

Tau
Pro: Took these guys last year so I could just run with the same list as then.
Pro: I have a fair amount of extra Tau figures, some painted some not, so if I decided to make changes to last years list I'd not have any cash outlay to worry about and minimal time to get extra stuff painted.
Con: I've never done very well with the Tau at Tournaments in the past so it may be shooting myself in the foot even considering taking them.
Con: Kroot.......they're fugly! I've always loved the look of the majority of the Tau models but the Kroot figures just don't appeal to me so I'm adamant that I wont field them, the trouble with that outlook is that they seem to feature in pretty much every "competitive" tau list out there so I may be loosing out by not taking them.
Con: Dated codex

Blood Angels
Pro: I have a 1750 point list all painted and assembled so no work would be required with these as long as I choose my list accordingly.
Pro: This is a recent codex and as such is geared up to take advantage of the current rules edition.
Con: The 1750 list I have is pretty much all jump infantry with a few Land Speeders, whether this would compress down to a reasonable 1000 point list is doubtful.
Con: I have very few figures asides from the 1750 point "Descent of Angels" list and changes such as Razorback spam would involve a significant cash outlay.


So there you have it, any suggestions to prod me along the path to a decision would be, as always, appreciated!
