I would suggest go for 200 and divide them b/w EF and Rafale.
EF:126
Rafale:74
yeah, yeah .. i know there is no split of order and all those stuff but that is not the hardwritten which we have to follow.
Now if we go for above configuration there is lot benefit we can get.
First there will be commonality b/w LCA-MkII and Ef if EJ get chossen.
Also french have some say in EADS and they are involve in Meteor projet which go to both EF and Raf,so common weapon.
Also IN go for their seperate MMRCA and they can very well chose Rafa.,then no. for Rafa will go to about 120.With this no. of Rafa we can very much indulge french into the kaveri project and develope that for further variant of LCA,MCA and even Rafa.
Another thing will be speedy delivery with two production sources and HAL we can induct all these fighter around 2022.
As far as maintenance and logistic we can ask both the vendors to have common radar,IRST,EW,etc...,as much as possible.
And all these goodies will be going into LCA to some extent so it will further decrease the logistic issue.
Well all n all it all can be mere speculation....
