IMO, I think he tries to say that all this airflow increase hip is kind of debatable, goes with each one of us preferences and dislikes, I agree.
When I said I have a 100% more airflow is IMO, I don't own a wind tunnel to prove it
For example, If I don't clean my SS screens or replace them I don't get a fuck of airflow, If I let too much oil and so on get stucked in any stem, glass or wood, modified or not, your airflow, wouldn't be the same.
Totally agree at @stickystones here. It's all in our opinions, it's totally subjective and biased to different
people.
Testing done or not, advertising and marketing strategies plays a huge role in peoples minds too, it's their "bread & butter" like they like to say here,and they are going to put on top their products.
Some wil support PV, other's Ed, some will never care... but as he said, we ALL totally agree that Ed's stems loads are bigger
, very well done Ed
