Race bike?
The Soda is too flexy, if you’re trying to put down shit loads of power you’ll feel it on every turn of the cranks.
Ti 456 I find to be awful with 100mm forks on it. It has a low front end with 140mm forks. 100mm on the flat feels like your face is ahead of the front wheel.
Hummer, for all it’s heavy (relatively…3.6lbs isn’t really heavy), it’s also stiff and direct and works well with 100 and 120mm forks.
TBH though, Airborne (AKA Van Nicholas) is the best bet. Setup for 100mm forks, lighter than all of the others (same as the Soda IIRC) and as stiff as the 456 but more compliant than the Hummer.
I’ve owned all of them at one time or another and currently use an Airborne Lucky Strike (Van Nicholas Zion) as an XC race bike. I use the Ti456 as my “day rider harder than full sus” bike.
The Ti456 is a mare to get working woth some bits of kit though. Chris King rear hubs, Bars and Stems etc…
