Thanks for the article! It explained a lot. I'm 186cm tall (around 6' 2'') so I was thinking of getting an ax of 3' (90cm) since the last axe I used was really small. Would you recommend this crampons?? http://www.amazon.com/Crampons-Altitude-Slip-resistant-Strengthen-10-Teeth/dp/B00PA6UNHY/ref=sr_1_18?ie=UTF8&qid=1417398861&sr=8-18&keywords=crampons+strap+on#customerReviews

They're strapons, so I think they would work. Here in Colombia the climbs aren't really too technical, so I wouldn't need something too fancy.
