Is there a reason why the Blend Technique is now with the EndoSequence files instead of ESX files? My understanding is that the ESX files are ‘better’ than the EndoSequence files due to having a booster tip? Is this still the case? Do you use the size 15 ESX file to measure working length at some point anymore with EndoSync or just use the size 10 hand file to get working length with this protocol? Thanks
