I usually am able to bounce a Neptune on most THS.
Depending on your specifics, if you like the Venus' reaction, you can stick with the same core shape with the Neptune (weaker cover).
I have however drilled a few Neptunes, and prefer the stronger layouts over the tame ones for this ball. (for me the weaker drilled ball seemed to labor alot more)
