@neilB I use FRIN. But it is not only because the TER is lower (.19%). I chose it also because of the question that you raised in your original post about concentrated holdings: FRIN uses the FTSE India 30/18 Capped index which means that the largest company is limited to 30% of the holding and the others are no more than 18%. I am not sure it makes much of a difference though 
Of course, if you are a index purist you may not agree with the capping. But there you go … you have lots of freedom in deciding what you want.
