Nice, well done. The notch is as far as I got on a very hot day several years ago; a time my brain was fried during the hottest day of the year... and decided impaired judgement would make the Lions attempt an unwise move.
Although West Lion summit is called a classic 3-4 class scramble in Matt Gunn's book, it does require rock climbing and pathfinding skills and you may easily go off the marked trail and end up doing low to mid five climb. That actually happened to my husband, but he used a rope to protect kids. Even following markers means you have to negotiate several exposed sections. We have been doing rock climbing for the last two years and have the skills and the gear, but the descent was still somewhat uncomfortable for me.
