Sidemount is progressing towards a greater level of standardization nowadays. There are common concepts and configurations now settling as standard... the approaches of Steve Bogearts, Steve Martin etc show this....
Good comment. There is a slow evolution that is making things more standardized, and the "tweeks" are slowly being homogenized with these systems. The only thing that scares is the possibility of a decrease in innovation. For example, some systems are rigid and altering them is discouraged unless they come from the founder,or at least this may be inferred.
