Yep, agreed.
I missed your post on page 2 because the thread was well advanced when I commented and I skipped ahead, but if the two of us dacron users can point this out and the guy (McPherson) stating that dacron is inherently dangerous for this reason missed out on the incredibly obvious, what does that say about his qualification to comment on fillers?
Not much. He hasn't used it.
Which is why the nonusers should refrain from "expert analysis"......they'll goof things up. And theory gets substituted for actual, factual use, which isn't much of a trade.
"One can disagree with McPherson certainly, but dismissing his credentials out of hand because one disagrees is a bit over the top."
I'm disagreeing with him here because he doesn't know what he's talking about, so yes, I'm dismissing his credentials to comment on the use of dacron fillers. Certainly an actual past user of dacron as filler wouldn't state what he did.
