If you haven't climbed on a 9.2mm you will get a shock, they are impressively light and responsive. I normally climb on thicker single ropes, but wanted a boost to my climbing, and this 9.2 and a 9.5 will definitely do the trick. Thicker ropes will often last longer especially if your heavy or your not careful with abrasion and rope drag. Having said that lightness is key and King, on the on sight and for long red point stamina suffer 'fests'. This 9.2 is in a 90 m version and the package is tiny, so this rope and a big bunch of light draws will take up less room in a plane or as your kit than a 10mm with sturdier clips, it's obvious but there you go, how often do we compromise. I don't intend to compromise this year. The added benefit of a 90 m rope is you can use it double and still get up lots of trad routes in the alps or bigger cliffs, just understand some simple math-thats right its 45m doubled! You can do 45 m abseils or if you are pushing it slightly longer with stretch!
