Particle system trail "Blind Spot"

I’m having a problem with the trails on this particle system, it’s leaving a rather large circular “blind spot” around its epicenter.

Here’s a GIF of what it looks like (with one-tenth timescale):

And a screenshot of the trail settings:

Just my 2 pennies: Use a “circle” emitter shape with negative start speed. Fine-tune the circle radius until the blind spot is no longer visible.

This worked, thanks!
