 I guess it depends on the mono pre you buy. FM acoustics I'm dead.

Graham Slee is OK at best
get a good mono cart like miyajima zero, that will have the biggest effect
System consists of an amp a preamp, 2 speakers a turntable and a phono preamp, Also some cables and power cords and a really cheap cd player.

I'm sure you're right. I would certainly hope there was a big difference in the performance of a $2000 cartridge compared to a $200 one.
But it doesn't matter to since I'm not spending those kind of bucks for mono. 
What options are in between?

  Check out the Graham Slee first. Oh yes the Miyajima is a great cart however the Grado at $100 is no slouch to start with. You really can get some great advice from Rob Wyatt on mono. If you speak with him mention me.

I'll contact Mr. Wyatt and pick his brain.  Thanks for the tip.  I emailed Boris at Vista to see if  he had any interest in designing a mono pre.  He has done such good work with the his stereo phono pre's at an intro level price, I thought I'd see if he might do something similar with mono.  He said that the curves were so highly variable that it was hard to get good info on the early 50's to late 50's stuff. He had looked at it and decided not to pursue it.  I've got the G.Slee unit coming next week and will see what it yields.

Why can't you just use a single channel of a stereo preamp for mono carts?

You can.  Or in the case of the Denon 102 cartridge, the post of the cartridge are extra long to allow two leads on each post, sending the signal to both channels of your stereo phonostage.  But a dedicated mono pre, or a highly adjustable stereo pre, can equalize to match older curves (in theory).  My buddy's Graham Slee Revelation M phonostage has setting positions for Decca vs. Mercury vs. RCA- don't know how effective they are.

Not directly.  The Graham Slee I meant to borrow has been out of pocket.  But I did read an interesting article the other night about the Denon 102.  One of the reasons it rough records more cleanly has to do with the orientation of the magnets in the Denon only pick up in one plane (horizontal) and most scratches result in vertical displacement.  On an older mono vinyl, there is no music information vertically.  A stereo cart has magnets oriented in such a way that they do pick up a scratch vertically.

What I meant to say was it PLAYS rough records more cleanly.

Exactly why one needs to be careful when buying a mono cartridge that it is a true mono design. A number of the carts sold today as Mono are simply stereo carts that are wired to sum the outputs of the left and right channel into a single mono signal.  A summed mono cart will read the scratch as the stereo inards are reading in the vertical direction. Of course the advantage of a summed mono cart is that it will give you a mono signal that contains both channels if you are playing a stereop record. But if you already have a stereo cart and are buy the mono one as a second unit just for mono records, be sure  that whatever you pick is a true mono design. Like everything else, you need to match the tool to the task at hand.
Remember, it's all about the music........

  Correct Tom. Can you say Myajima ? If one owns numerous mono LPs get another TT or second arm and use a mono cart. No turning bach ! Such a staggering difference especially with respect to noise NONE ! Music is deep in groove not on sides like stereo.
