Familiarity: I've put it through the wringer
I love these crampons. I've had them up to the top of Whitney, Rainier, Shasta, and a bunch of smaller peaks, and they've been awesome every time. I got the anti snowball gizmos for the bottom, and they work great, but I'm pretty sure you could make your own for about $5 (it's a cheap yet effective piece of nylon reinforced plastic/rubber that prevents snow from sticking to the bottom). They're fast to put on and take off, and I think that because they have less severe teeth, they tend to pull less harshly on my feet, making me less likely to catch a tooth and trip and also rubbing less and causing less blisters. I've used them in plenty of conditions where other people had the most aggressive crampons, and I had no difficulty. I don't think you would need front pointed crampons until you got into like 60 or more degree slopes and they'd have to be solidly icy (I went up some steep steep stuff on Whitney and Rainier and the crampons were not the problem). Frankly, I'll always carry my Kahtoolas rather than a more aggressive crampon. I have the steel, and I highly recommend it for the odd patches of rock and scree you will inevitably come across. I never clean mine and they are not appreciably rusting (a spray of wd40 will help if you're paranoid), and so I will never clean them because they will already outlast me. I recommend the steel just so you don't have to worry about them... they're already a light crampon. I have no slipping issues like others have mentioned, in fact, they're so solidly affixed to the boot that if you're boot is not laced tightly, it (or any crampon I've used) will yank your boot around so much you'll get blisters. Buy this if you tend to be the person who prefers agility to redundancy. If you're typically the only one with regular boots when everyone else has hard shells, these are for you. If you're climbing an ice waterfall or taking an expedition to the south pole, look elsewhere. Buy these!
