Weight cut for MMA fight?

So I've been approached with a fight I ordinarily wouldn't have considered but need some advice from someone's experience as a fighter or coach. I usually fight at 155lbs or 145lbs...I walk around at about 160lbs (give or take a few pounds). The guys at 155 tend to be much larger, but sometimes I take it just to have a fight if it's been a while. The weight cut for 145 is no big deal...I took a 145 fight on a week's notice once when I was weighing in at about 157lbs and made the weight with no problem. I was asked if I'd like to accept a fight at 135 about 3 months away but I wasn't sure whether to accept or not. What weight do these bantamweight fighters usually cut from? Do they usually walk around at abou this weight? Can a person at around this size cut that much weight...I know the bigger weight cles cut drastic amounts of weight at times, but is it possible for the smaller guys? I'm already lean but can cut some flab away due to the increase in cheeseburgers lately and tend to build up bulky muscle m at times. Some real advice would help not the crap about "cutting weight is unhealthy" from guys that have never done it. I already know all that stuff...Thanks in advance!
