Technically, yes. They are different. Some people cant feel a difference (one of my friends), and some can. (me) Its pretty much just weight, but the texture on the Orange feels different then the White and Red and all the protostars. I think that the Northstar is better by a lot, but It is completly preference.
yeah… go with the NS. the difference is SO SLIGHT. but i believe the ns is celcon, while the PS is poly carb. and celcon grinds better than poly carb. But to me, they are VERY VERY similar
Northstar all the way! i love the Protostar but the Northstar just has like everything. and it is also so i mean so smother than the Protostar. So yeah i would choose the Northstar.
After using a white one and an Orange one, and a protostar, the white feels exactly the same as the protostar. Its the Orange with a different texture.
