Thanks for the ten year old video of a DH bike. I’m sure nothing has changed in 10 years, especially comparing a DH bike to a modern trail bike.
I know I don’t have to lock out any of my bikes ever & bob is not an issue ever. Always run the rear shock fully open.
I can either sit & pedal or get out of the saddle & hammer - no bob to worry about. Just crisp response.
I do lock out the forks when honking out of the saddle on both bikes, but when out of the saddle smashing away with the fork locked, both bikes feel solid & efficient.
Indeed, when I swapped out the shock on the TBc for a Monarch I chose an RL version as I never use the trail setting. The trail setting on a VPP or DW isn’t needed.
I’m not sure what else I can say on the matter...
