Noooooooo!!!!! Can of worms!!!! 😯
I reckon the best handing 29ers I have ridden have slackish ha and short chainstays (sub-17″). ie stable going down, but still climb well and nimble.
I think longer chainstays are fine with a steeper ha as the quick steering front makes up for the longer rear.
It also depends how you ride; I’ve definitely found shorter chainstays work well for standing ss climbing.
The Trek Stache looked great – until thet revealed the geo. Slack ha and long chainstays. Very stable going down, but I imagine a pig in tight singletrack.
Canfield et al have lead the way in this; I do wonder if guys at Trek have ridden a Canfield?!? Kona seem to have caught on…
