Just placed an order on a 104m Delay

Can the 104M be fed into the loop of 104M for 2 independent delay lines or would you run them as two separate delays?
Also I have been listening a lot to the 108 Clusterflux and am very tempted by it's sound, would anyone recommend getting one?
Some say they can be noisy and am struggling a little with the noise from 104z but not too much and with several BBD's chained together?!?!, is the noise ratio comparable?
Currently in the set up is Voyager 102 Ring Mod/103 Phaser/104z Delay with the 104m on order.
Would the cluster flux be overkill with this set up? I hope not
