Hi. I've been skiing an O'Brien Andy Mapple Siege, the one before the piezzo (about 1998??), Carbon finish with his signature in gold, since about 2000. Will I benefit a lot from getting a slightly newer ski, like the D3 C7 (2010??)? I'v also been skiing the HO Adrenalin CDX for about 2 years now, but find it very heavy and slow to accelerate and almost too aggressive in the turn in. Any insight will help.
