In reply to James0101:
It’s generally considered a safe choice due to the aspect, but you do walk up the Allt Daim which means you’re exposed to NE slopes on the approach. It’s possible to take a high line underneath the west face after the descent from the ski area rather than dropping all the way into the glen, although the going is probably rougher. You’re unlikely to be the only people going that way tomorrow but not ideal to follow other folk.
Not entirely easy to find if there’s any low cloud, but there’s several options at a similar standard within a short distance, we climbed Gendarme Ridge by accident the first time I went there. The crux on GO is low down and then very pleasant easy climbing/scrambling to the top. It’s not really comparable to the Forcan, which has a lot of walking on it with some scrambly sections between. Golden Oldy feels more like a climbing route with a need to know when to pitch and when to move together with gear between each climber. If you pitch the whole thing you’ll definitely miss the last gondola.
Worth having your map and compass handy for the top as the summit of Aonach Mor can be a scary and disorienting place in cloud, with a fairly small window for error. It makes you want to veer N to the ski slopes quickly but that takes you very close to the top of Easy Gully and potentially large cornices. Following the lines in the Walk Highlands map is fine in summer but for winter I’d want to be about 100m SW of it (particularly between point 7 and 2) and take the same dog leg.
