The best Alpha for getting things done, concentration and clear thinking?

[Dsouza]

Say you're a musician like me and you need to spend 6 hrs a day on the guitar and you need smooth , clear , focus.  You can't be moody or you'll muck up a delicate job.  You need to remain calm, extremely focused, with laser like  concentration.  It helps if you can think ahead while you play instead of just in the moment as great guitarists are not just creative but also logical thinkers.

I am wondering what the king of the alphas would be for this task:

I have:

a) A314 classic
b) AT
c) TUSC
d) BW
e) Titan

I've seen great results with TUSC.  API on the way (Just ordered today!)

I don't think mones are going to help with this.

Armodafinil or low-dose (like 5mg) adderall.  I get both from my doctor and alternate

Not an alpha, but you might try Treasureful Shine

TAF whatever that actually was from Androticsdid wonders for my focus
