Serious question. Open to one and all - especially anyone that might have some insight into the nuts and bolts of the manufacture process, or maybe the marketing types who might see these features as part of an overall branding strategy:
What would prohibit the company from giving consumers the choice between the new caps and the 'classic' version? Clearly, some are passionate about the old ones. And the new ones have their proponents, too.
I would imagine that the manufacture capacity doesn't exist - that is, the fabrication process is set up for one, and there isn't a built-in flexibility that would allow the same machine to make saws compatible with both.
Or maybe not. Maybe it's a branding thing - part of the overall "Stihl is a leader in innovation and engineering" message they like to communicate.
In an ideal world (which this is not) potential customers would have a choice and the market would be the final arbiter.
As it is now, the non-flippy person wanting a Stihl has the option of embracing/tolerating the caps to get the product he wants - or is faced with the option of going with another brand.
Just a dispassionate, disinterested, and objective look at the business side, I guess.
THALL - you might be able to generate more light than heat on this.
