Is it a feasible option to take the lines to & from a chiller, and put a tee in them, to send the water to 2 tubes?

I'm just thinking that a step-off the CW6000 to the 100 watt tube might be better than using a 3000 unit I have spare?

I know dual outlet systems exist- I just don't have one! The makers of the new laser said the CW6000 is ONLY for the 180w tube.
I'm interested in other opinions, because the CW5200 runs fine on our 130w system, not varying when run at 20mA all dayand looks like it could handle more load...

Thanks
