I go for the babe behing the counter. Nothing beats a pretty smile.
When I can't find that I go with knowledge of bows. I've been to Len's shop and it's one heck of a shop with someone who knows his stuff. For me it's too far away to go there regularly (6hrs). There is an awesome shop in Dunn, NC. It's only 1.5hrs away. The owner knows his stuff and has a good selection of equipment with a great lay out. It shows he has put a lot of time and effort. When your in sales presentation is key.
