Ideal injector spray pattern *VIDEO*

I am getting injectors for my N/A B20 vtec and am curious which of the following 2 spray patterns would be more ideal?
Both of the injectors in the video are 320cc Bosch

Thanks.

The cone shape on the left. The "laser beam" pattern will have a velocity induced harmonic that will create a fuel reflection off of the valve backside and cause a "miss" or stumble. I experienced this myself in my Jackson Racing Supercharged GSR with RC 550's. Took them out and swapped in a set of cone patterned RC 650's... problem gone.
