And what size?
G12 newmatic fit nepal extreme very well IMO.
The only bugbear I have with G12 / G14 is the front point protrusion could be a little better but it is OK on larger size nepals with the newmatic fitting.
The crampomatic fitting is OK to start with but as the toe bail bar bends and the soles wear down the front point protrusion gets worse to the point that even adjusting everything to give the best results a new toe bail bar must be bought to get the front points protruding enough. The newmatic fitting doesn't have this problem and is quicker to get on, more secure and has less 'play'.
I guess under about grade V G12 will do everything G14 will do nearly as well, but will perform better on poor snow, is more suitable to alpine and better for walking. At grade V and above you may want vertical dual points for ice and a mono for rock as the positives start outweighing the negatives. Which crampon design is best for you does to some extent tend to depend on your asperations, how quickly you think you'll realise those and how deep your pockets are. If you are operating on a budget and think you'll be pushing up to grade V quite soon I'd probably opt for something like the G14.
I find most people with vertical points that can be adjusted between 1 and 2 points dont actually change the set up very often (including myself), something you may want to bare in mind.
