Next open run will be Memorial Day. Members of course, will be on the trails before that and we also have some trail cleanup to be done. We're going to get that playground crossing fixed once and for all (although it's hard to plan for the sort of flooding barrage of rain we had last summer)...
With a mostly stock drivetrain, I think Aussies aren't likely to break (referring to the "piece of s***" comment).
For a really serious rig tho, spools are cheap and tough, no doubt.
I have an Aussie in the front of mine and a lock-something in the rear, and you would not believe how loud...

Here's a couple pics I have laying around... don't know if it helps you or not. (pickup\4runner shafts here)
on the left is a IFS front shaft, on the right is a SFA shaft. You can see how the SFA CV has a greater operating angle.
