Replying to Need help for choosing the right ski length [Armada Al Dente (or alpha x]

Hi, I'm Arsène, 18 years old, +-84kg (amateur bodybuilder), and 182cm long. I've been going on a one week ski vacation every year with the familie since the age of 3. This ski vacation I did backflips and 360's on the large jumps and I wan't to take it to a another level (corks n stuff). I'm buying myself a trampoline and I plan on going to the indoor skiing funpark every month/week. So I will be mainly skiing park with them.

Now, Al Dente's come in ski length of 178 or 188. Isn't 188 cm to tall? This ski vacation the ski dealer lent me alpha one 2011 of 182cm and saying that they would fit me perfect. So help me decide wheter I should buy 188cm al dente's or 182cm alpha ones.
