3sixty.2 3-way Front Stage

I'm currently running a 2 way front with sub off my 3sixty.2 and am going to try a 3 way front. With the 3sixty.2 would I be better off:

Using the center channel and running my midbasses mono, they would probably be somewhere between 65hz to 275hz, and using the front and rear channels on my mid and tweet or,

Use the rear channels on my midbasses keeping them stereo and using the front channel and letting the mids play from 275hz up and using a cap on the tweets.

I will be using the zapco ccompetiton 6.5's for midbasses, and hybrid L3's and L1v2's. Just wondering if the loss of stereo on the midbass will be very noticable. Thanks.
