Artillian might be a little over-hyped on YouTube. It is a good system, but it isn't perfect.
The artillian grapple is heavy by comparison, esp when every pound matters on a BX, about 270 pounds. The Artillian style is more of a box frame, so grabbing small quantities of loose material with it can be a little tricky. I use netting to allow it to pick up small things like leaves and oak branch pods, it does well with trees, limbs and brush.
I think their implements work best for people without SSQA. The artillian system is kind of a pain, you are taking stuff off their adapter plate, and putting stuff on by hand. This is defeating the purpose of having SSQA. This is why I would never use them for forks.
They claim their forks are the lightest in the business, they arent.
I do love their mini stump bucket. I dont use it often, but it's really handy when needed. It beats storing another implement on a big frame, and its only like $300. In this case I like the system, the grapple is used all the time, but in the rare event I need the stump bucket, i can swap it out in 5 minutes and its not consuming any storage space.
