I'm sure that a few folks are going to wrinkle their nose at me replying to this, responding primarily to your first post. Thought that we are in as good of position to answer as anyone, and I will try my best to keep it objective!
Sport6, please do not hesitate to ask me to remove if you feel it will get in the way of you getting the info you seek. I would also like to say that we are not really trying to compete with Wahl in this market. Just providing an option, particularly for customers that are already buying our other skis and/or carbides for their IFS skis.
Here are the major key factors both ways in my opinion:
1. Derby Skis come fully assembled, which takes about 1.5 hours.
2. Derby Skis are CNC machined, including holes for precision. Wahl skis come as a kit and you are drilling your own holes.
3. Derby Skis offer custom powder coating/anodizing options, and loop colors.
4. Wahl skis come in a wider extrusion to accommodate wider IFS spindles and Derby Skis are currently 2" extrusion only.
5. Wahl skis pretty much come one way, so you order them and they will arrive in a few days. Derby Skis are often custom, so they are pretty much built to order.
Please let me know if you have any questions!
