Nice one OP.
I’ve never owned one, but I love the Anthem 29er. The numbers are deeply unfashionable for a modern trail bike (100mm travel, 71 degree head angle and 462mm chainstays) yet everyone who rides one comments on how capable it is going downhill.
I think your comment about stability (which is probably partly down to those unfashionably long chainstays) is spot on. Some people like a less stable (I think the term is “playful”) bike, but for those of us of a more nervous disposition that “playfulness” can just have us hanging on and praying for the descent to end. A more stable bike gives you the confidence to more about a bit more, which can really make those descents a lot more fun.
Anyway, I hope you continue to enjoy it.
