Me/E or E/Me Speed or Quantity (and more)

First off, this is my first post. So, hello to everyone! :D
Alright on to business.
So I have been looking at the classes for a while and think that mesmer looks like it would be really fun to play. I know it is tough for beginners, but I figure I will go through some tough times but there will be a light at the end of the tunnel. So on to my true question. I want to be a Mesmer and an elementalist.

Now I know fast casting can help a lot with some of the longer elementalist skills and is just usefull in general, but energy storage looks good too. I am wondering which I should go for if I plan to use 5-6 mesmer skills and 2-3 Elementalist skills. The elementalist skills would most likely be highly damaging ones, just so I can through my weight around a little. These skills however use up a lot of energy. So I am wondering, should I go Me/E and get fast casting or E/Me and get energy storage.

Thanks

p.s. I like the look of Mesmers more

p.p.s. Feel free to add anything else that may influence my decision.

Worrying much about energy isnt a problem if you are of any part a mesmer. Mesmer inspiration skills help you get your energy back, especially with the skill energy tap and energy drain.

Drain Enchantment and Inspired Hex are also lovely ways to gather energy. It helps you AND helps your party (no more hex on friends (or you) or no more enchantments buffing enemies).

Let's face it, energy you can get a lot of with any part mesmer. But no other class or equipment can consistantly give you a 3 second Meteor Shower.

Alright, it seems like I will be going Me/E. Thanks for all the help guys. A build should be comeing some time or another.
