In reply to Andy Clarke1965:
No Fergal, rather the opposite. If you get some modern, well designed crampons that are either dual point, mono point or modular (so can be either) I suspect you'll have a great time climbing with any of them! Pick which ones fit your boots well and look really cool - they will almost certainly be the best!
I reviewed these Edelrid ones a couple of winters back:
http://www.ukclimbing.com/gear/review.php?id=6227 I wouldn't recommend them for the reason I go into in the review but they do an all steel version which might be worth a look - the front point changing system is so quick and easy (unlike, say, the Terminators I've used for years and years) you could literally take the allen key in your pocket and change them from dual to mono at the CIC hut should the mood take you.
I agree that the prices do seem to have gone up noticeably over the last 5 years or so, so it is an investment. Climbing Technology are well worth a look from that perspective. I really rated their basic 12 point ones a few years back
http://www.ukclimbing.com/gear/review.php?id=3300 as basic all rounders (although I climbed short bits of vertical ice ok with them), mainly just because of the very fair price - but their more technical model this winter looks good.
I actually started writing an article for my blog a couple of years ago about dual versus mono but never finished it, maybe I should as its something that regularly gets discussed. I did do this quick post way back when that was prompted by a UKC discussion on this very subject
