the initial tension drop isn't that much bigger than with most other strings tbh. BG66UM is at the same level I would say, BG80 slightly(!) better, BG65 and 65ti even worse imo. During a tournament, the pros will get a fresh string job for each match so frankly, they don't care at all about that tension drop. They order their usual tension and they will get it with the same effective tension as they are used to.
