In reply to andyd1970:
I believe the Lynx is the only one that is easily converted to monos. G14 are the second best and the Cyborg is a PITA.
Of the 3, I'd get the Lynx, as it comes with both step-in and also the basket thing.
Another option to consider would be Austria Alpin SkySteep with the basket as an added extra. I'd also consider the same approach with G14s (Grivel sells a step-in to basket "bail").
For the record, I absolutely love my Darts, except for the fact that the 2nd point configuration (they're not aggressive enough). And I believe this is also true for Lynx's. It's even worse for G14s (which I also own, they're old though and used for drytooling and early season mixed). From what I remember the Cyborgs aren't any better.
Grivel Rambo 4's have a really ice point config, but the pie-cutter is something I'm not keen on (luckily the Grivel Racing bolt-on crampons have the same config, which I happen to also own).
But as stated, I know rock the SkySteep and it performs really well. The only thing I don't like about it is the weight and also how it folds down, when compared to the Darts. But those are the things I'm willing to suffer for the benefits from the points and also the rest.
