I skied on Pistols, and swore I would never ski anything under 90 underfoot again. Then I got maden's, now I will never ski anything under 100 underfoot again, and my park skis seem MINI. Next year I am getting some ON3P fatty jibs, being 115 underfoot, and then hopefully some hellbents.
Trust me, you don't need to justify it any more than the fact that it will be sick. Plus, Pollard would agree that it's a good idea
