I owned a Neptune at one point, and I own a Natural now. The Neptune is WAY stronger than advertised. Very very aggressive off the dry. I had two completely different drillings for it, and each one was over-reactive and jumpy. I think the best bet for super dry lanes would be the urethane or older resin equipment. I find myself using gear with Storm's old Accu-Tread coverstock on the dryer stuff - still that familiar resin reaction shape, but the ability to have it on toasty lanes.

Some stayed in the foothills, some washed logs like teeth.
