vlt peer routing and ip helper configuration

i m planning to migrate to dual configuration of S4048-ON with vlt per routing and i m wondering what is the best configuration for ip helper configuration

should i put the configuation tto two cooperation vlt router or should i put the configuration on the one who got the ip adress of the default gateway.

my first guess is to put the configuration on both but then i will got two request to the dhco server.

am i right?
