What are you planning on using the tripod for?
I had that tripod for awhile and other then 8x bino's I wasnt happy with it. Also, it's super short, so it wasnt able to remove that many leg sections to lose weight.
That little head that is included in the package is pretty good though. Try it before you invest in the Outdoorsman. I wish I had. I'd gone thru all of the different Outdoorsman heads by the time I tried that Sirui. I ended up liking the Sirui and it's what led me to going back to ball heads, with the addition of the integrated pan function. I'm 99% sure that it accepted Arca Swiss and RRS style mounting plates.
I ended up with the Sirui T1205x and was able to remove more legs and the long center column to shave weight. It ended up taller and lighter then the 005x.
