There are a number of threads here asking the same question - do a search and you will find lots of opinions on pros/cons of large versus medium.
I am your height and same inseam, and I went with a Large frame. I run a 90mm stem and am happy with the fit. We could both go either way though - large or medium. Many recommendations on this question are based upon how you like to ride - medium will be more 'flickable', etc.
If you can, the best thing would be to go demo both a large and a medium and see which just feels better - so much more valuable than anyone else's opinion.
Best of luck, and happy holidays!

tks guys I did look at the old posts and unfortunately am more confused than ever cos I could swing either way. Wish Ibis could make an 18" and make a lot of folks happy 
.....I'm now on an 18" Kona King Kikapu.
I'm leaning more towards the large for stability and riding comfort but worry I suffer on the climb. Where I ride mostly, it's tight technical climbs with not too much Downhill so I was even contemplating going back to an XC platform vs the Mojo which is more like an All-mountain build!

It's a tougher decision if you are between L and XL. XL has a pretty long wheelbase that slows down handling. For your height I think Large is an easy choice over Medium. If you got the Medium how long of a stem would you get for it? It seems like it would have to be over 110mm or you'd be cramped.

You will be happy either way. I'm 5' 10.5" w/ 32 inseam riding a medium with 100mm stem, and I've had nothing but fun on it for 1.5 years now. I demo'd a large w/ shorter stem, and it didn't climb as well (front end got too light on steeps), and was less nimble on tight 'n twisty trails.
But that being said, I could have probably gotten the large set up to an decent point for climbing if I had more than one day on it, by playing with headset stack height and seat rail adjustments. The large would be better on non-twisty descents, and large gives you more flexibility if you want to experiment with shorter stem, which is certainly a trend that many have embraced.
In your case where it sounds like you are more concerned with technical CLIMBS than descents, the medium with longer stem might be better, especially if your climbs are steep. But either can be set up to work well...in the end we're only talking about ~0.75 inches here. I'd also encourage you to call Ibis, as they were helpful to me when I made my decision.

Greetings!
I too faced a similar delemma several weeks ago. I was not able to lay hands on a Ibis Mojo, so I had to go seat of my pants and buy without a ride on one. I think there are several factors that should be considered, this knowledge was gained by personal trial and error, and comparing my new bike and the sensations/feedback give to me by the bike. There was also a bit of blind luck involved as well.
First you must have some sort of an idea on if you like a larger or smaller bike. If you do not know that just climb on some and decide what the lesser of the 2 evils is, larger or smaller? It does not matter what kind or brand, just ride some bikes that are of different size. Consider if you like to be errect, spread out, if you perfer to glide and ease a bike or to manually handle it, steer with the bars so to speak.
I am 6' with a 32-33" inch inseam, or sole to sack as you put it! Those measurements would pretty much say Large to most, or so I'm told, although there are some who say Medium?
I like a large bike, I have 2 other bikes that are XL, or 21.5" frames, I opted for an XL Mojo.
I am super glad that I did, the XL mojo is slightly smaller than my 21.5 Trek Liquid. When I received my Mojo it came with a 50mm stem (that was the blind luck part) although I am going to go with slightly longer stem for comfort purposes I could not believe the handling characteristics that come with the 50mm stem. The ease of lofting the front end with no notice. I have a 110mm stem on my other bike, let me tell you as streched out as I am on it, it is quite comfortable but if I suddenly happen across a situation that requires an instant leap, or huck in order to avoid a front end first plunge....to bad, I am stuck like chuck and just have to go with it. With a 50mm stem it seems as though I can be actually dropping off of something and still pull or pedal the front end up and drop off rear wheel first if that is what I want to do. Of course this could be the MOJO too?
Hopefully all of this makes a little bit of sense?
Really just consider what terrain you ride, how you ride, what you like, and take the plunge.
I think if I were you I would consider the Large!

I demoed both M and L and finally decided for M with 10 cm stem and setback Thomson seatpost. I am 181 cm tall. If you want XC bike and you are between sizes, take definitely smaller one. If you do not intend it as XC bike, than it depends ... ? I do not know why but when you ask about bike size, mostly those who chose larger ones reply and advice you to follow their way. Read carefully all replies of Tall Tom of Ibis in the history.kakachi said:
