Thanks to all for the extensive work to put these together.
Based on those videos my opinion is that I will need to see a side by side for myself. Currently I am of the opinion that few pins warrant the cost of anything more than standard, but if you are going to go with a high dollar glass, then PDI has my vote.
It all really comes down to price point. If I am going to spend more than $40 then for the money I am going to buy the PDI because it is far superior than the phooglass in properties and is not really substantially more than the phooglass.
That said, if Phooglass only cost $100 then I would likely fit all my pins with it as the minor decrease in reflectance and sound dampening would be worth the extra $60 over standard.
JMHO.
