Contracts on W2, or 1099 or Corp-to-Corp which is better really depend on your personality and the take home money difference worth it. you must do the numbers before you make any of these decisions to pick one.

roughly, Switch to Corp-to-Corp if it gets you more than 8% of Contract on W2. This calculation works fine if the benefit under W2 didnt include medical (may be you get it from your spouse) or 401k (if the employer match is very low) and your employer is only paying their part of FICA (Social security tax and Medicare).

the forum gone a little bit twist from my original question, but this is definitely something worth discussing.

one thing definitely I take from it is BI has good future , even more with Big data.
