Risky Bussiness

Now that I got a job that I like in a great company, another company called in and asked me to go for an interview..A pure Engineering firm which does R & D, consulting and also equipment design. The greatest thing one can desire..The interviewer was astonished by my research back ground as well as engineering!!although I am not sure why he was so suprized;)but he kept on telling me how it would be good and great for me to join them;)and he asked the other guy why they didn't ask for me before!!!anyways its good to have that power:)well I guess I have to write the pros and cons of this situation and see how it will be.so pray that I make the right decision. I love my current job..I absoultely love my supervisor and my team. They are the best..I don't know what to do..
