Thanks Steve. You and Dale are are the first sites I visit for PWD stuff. There are no other vendors that come close when it comes to both top quality and value! No, I'm putting together a speed tips handout for a workshop I'm doing in a couple weeks and including a list of vendor sites. I know Derbydocs is shuttered and now I'm hesitating including Derbychamp since the site's been down over a week now.
I can not say that I know anything about their site. The vendors that sponsor PWDR are great places. Please don't forget Derby Monkey, Derby Dominator, and Pinewood Gravity. We are blessed to have so many great sponsors with a lot of great information here.
If you are looking for a handout to give away. I know that 5Kids posted a handout he gave away at one of his workshops. Maybe you could contact him and see if you can use his. It might save you some time and the information is great for scouting.
