If a quiver is set up correctly, it can make skiing that much better. Also, if you ski 75, 100, or more, days a season like a handful of people around here, yes, it's totally worth it. I've got 5 pairs, but they all serve a specific purpose:
191 ANT - pow/charging
189 Gen1 Pistol - AT
186 Spat - deep
183 M103 - everyday resort
179 PE - park
