I had occasion to need to swap out my fly on my Hennessy
First... I don't think I ever got either a timely reply or
a reply that wasn't an automatically generated one from any
companies online email address. Hennessy answered it the
same day, with a live person.
Second... After I mailed the fly, supplying the tracking
number to them, they cross-shipped the replacement without
waiting to receive mine.
Third... They supplied the tracking number to me.
Very friendly service.
Cant ask for much more (Except free samples!)
