Different distributed shapes

[Major]

Hi

I'm new to Tyflow, and I'm in the process of making arrows that follows a path. The arrows needs to show the flow of certain machines.

I have really tried everything 3Ds max had to offer (I think), to try and make these arrows spawn on a spline and delete at the end. 

I have tried path deform, old particle system and now I've come to Tyflow. 


At first I made the arrow one object, but I couldn't make the arrow bend at the curves. Which it has to do.

So now I have this idea to make two objects. Arrow Head and then the body. (green arrow)


On the picture it's only the arrow heads that follow the path.


I wan't to distribute the arrow head first and then maybe 10 bodies after, at an evenly distributed interval.
So it looks like the longer arrow below (red arrow)

Put I can't figure out how I do that with the distribution settings.

I hope it makes sense

If there's a more simple solution, I'm all ears


Thanks
