Which TVS group company is best for longterm?

Hi all, out of all the Indian automotive groups the TVS group seems to be the best/most vertically integrated, as in has a hand in everything from manufacture of tyres (Srichakra) to wheels (Wheels India) to stampings which are not only bought by group companies but also several other major manufacurers like Maruti/Hyundai/Honda etc.

So my question is which TVS group company is the best to invest for longterm.

Ps: I am not interested in TVSMOTOR, their bikes suck. :slight_smile:

Thanks.
