Hi Payal.This needs to be answered carefully. While you are saying that you don't want to take a chance in terms of choosing your guide, it sounds like you make most moves in your life with extreme care. This is perfectly reasonable but it can as well be argued that there can't always be guaranteed result to everything that you do. PhD itself is an open ended project which may or may not make you satisfied enough.
I entirely agree that choosing a guide in PhD is as important as choosing a project and all the rest of it. PhDs have a combination of factors in it such as guide, project, university, funding and all of them may not be exactly be of your choice so an optimum decision is to be made by none other than you. I wish you good luck with that .
