It’s a catch 22, as part of the reason we all enjoy a bunch ride is for the rolling chat. The problem with a big bunch is that you can have multiple mini chats/ bunches going on and this can lead to disaster …
We actually need to be more disciplined in a big bunch .. never more than 2 wide, listening for calls and providing calls . The tighter and more in tune the bunch, regardless of the tempo, the better you can get the job done safely and all applaud each other at coffee.
