In reply to David Coley:
I soloed Muir (middle of TD) but have climbed TD, Nose and Salathe with partners, I've soloed most of Zodiac (long story). The aid on Zodiac is a little trickier but it's half as long and you can justifiably climb 3 pitches a day as opposed to 6-8 on TD. I'd say that unless your systems are super dialled and you're free climbing a lot Zodiac is going to be much easier than TD. Tangerine Trip is easier than Zodiac too, though they are both pretty busy!
Could always rope solo the Freeblast without bags as a warm up, you'll need to do this for TD anyway, hopefully the Heart ropes are there and you can just go up with a lead line and rack. If you can knock that out in 10 hours or so no reason you won't send TD, if you're slower I think a more aid based wall might be ideal.
Have you soloed many walls? Why not go for something cool and slightly off-beat like Dihedral/Horse Chute or New Dawn/WoEML? No traffic there so you can take your time!
Just musings! Take them or leave them.
