So with the new tuts out on H18, thought I would try something with these new SOP versions without resorting to vex which is what I like to do normally.

Also, thought it might be good for Houdini Newbies to play with/look at, since I'm not set up for authoring tutorials.

I haven't tried to see how procedural or not it is (different input profiles and path length) but I found I didn't have to do too much tweaking to resolve some issues so it's not likely to need much work for a tighter procedural set up.

I believe the most important one to look at (for varying path lengths) would be the Bend sops capture region parameters which should use some expressions for different case scenarios - as it is I just used the default setting of applying ‘N’ while working in viewport.
