QTR-Quadtone RIP

Hi,
I've always edited for QTR in the QTR Gray Lab profile and printed using QTR Gray Matte. 

I wondered what the effect would be if I edited in Gray Gamma 2.2 because I will still be printing in with the QTR Gray Matte profile.

When the file is converted to QTR Gray Matte for printing, surely it will end up the same?

Because most of the world operates in Gray Gamma 2.2, it seems logical to use that colour space in order to save changing profiles when sending files to other people - as long as the file will end up printing the same once converted to the output profile

Any thoughts would be appreciated.

Thanks,
Richard
