Mr CB
If you have time on your side and license then DO NOT GO for any sort of rating for atleast 1 year or so.
Reason - You will end up tied to a type that may not be flavor of that particular time or maintaining it might be too much for you courtesy Indian DGCA's ever changing rules in future.
My Advice - Play the time well & save for future upgrades of ratings and all.
Bhambri - You got pm.
