The 3X9 scram works great with brifers. My 3X7 sach is grip shifts. Never tried that hub with brifers, but it would proberly work fine as there is an extra click on the brifers for cable travel issues etc.
I meant more than brifers might not pull enough cable for v brakes , although I found that with carefull set up they were "ok" on my v braked Downtube folder that i fitted brifters to.
