Threefold Dilemma

I start this post being undecisive about the title..maybe I'll find it during the course of this writing. I remeber there are a few posts those are rotting in the 'Draft' folder, unnamed and unpublished. They might have fortune change today..God knows.
I've a lot of things runnning through my mind, probably because a lot has happened, a lot is scheduled to happen and some that I was told, may happen.
I got promoted last week, great! I'm happy but my rating sucks! I didn't slog my ass more than 12 hours a day or 10 months to get a 'CC'. I proabably didn't realize the bad-ness of my rating because it was capsuled in the sweet coating of a promotion and I had no idea of the impact it would be having on the money I would be making. Since I know now, the difference, it troubles me. I didn't get time to talk to my TL and thus, my manager, about this. My TL was not available for past 2 weeks because of ill health of her child, maybe Monday could be the day.
There has been no developments, as such, on my plans of getting transfered to Delhi(as if it is in my hands). This fucking project is getting delayed day by day and so are my transfer processing date.
The other day when I walked up to my manager to ask him to look for a project in Delhi till the time I serve this project, to my surprise, he offered me an onshore oppotunity. I was happy hearing that. I replied with a 'Yes!' the next day, since I asked for a day to ponder over it. The reply I got for an enthusiastic 'Yes!' was a faint 'Ok' and an unconvincing nod. That has got me thinking whether it is a 'lollypop' or something to defer my plans of going to Delhi, or there is actually some opportunity. I hope there should be some. I can't miss going to Delhi though , so, I'm going to ask for a transfer and might go onsite while I'll be Delhi. Sounds great!
I was adviced by a fellow roommate, a techie turned consultant, to hone my (non-existing) skills in Siebel. Being in a testing team, I don't have much exposure to this technology and I've been doing Lodestar testing almost all year around but hearing him say Siebel being a 'Hot Technology' I'm raring to try my hands on it with whatever time I've left in my project.
There is a 'threefold dilemma' though, the onsite opportunity that I mentioned above is in the Lodestar. If I choose to go ahead with Siebel, I might get (huge, as they say) returns in 2 years time but if I choose Lodestar and onsite happens, that would be great. In both of the said scenarios MBA is going to take to a backseat..I don't want that. I love Corporate and I love being a consultant. MBA is the only thing that can help me get that sooner. So, the bettter idea could be that I do nothing but take transfer to Delhi, do what I do i.e. Testing and later take a MBA degree and become a hard core consultant..then I can take as much onshore and as much traveling I want.
Last option sounds perfect keeping current situation develpoing in my hometown. Politics is dirty. Very soon, I hope never, I might be doing something which is not thought of and very different. That time has to decide, right now I won't prefer coming out of my comfort zone. If I'm forced to do so..uncomfort-ability would prevail then, for a long long time.
