I agree with darren that going for the max miles possible does not always make sense on a F Class ticket. You can get more miles by flying in Biz to Dehli then in F to NRT but your comfort level would be dramatically different.
The same aplies in almost all continents where scheduling and seasonality impact where you can go and how long your layover would be. There are many discussions on this in the past. My suggestion is to post an initial plan and you will have no shortage of advice of how to maximize your miles from there.

ps. also do not forget that visa requirements into many countries and your willingness to travel to the middle east will impact your plans!!
