<p>First off, what you get from CC are people’s opinions. So you need to look a little bit into the background of the people giving you their opinions. So, I’d say take Bonehead’s advice. He’s a MechE graduate of Illinois, and is, I believe, currently obtaining a Masters in Aero. Einstein, on the other hand, again, I believe, is yet to take a college engineering course, or any other college course for that matter. So, although Einstein is entitled to his opinion, I fail to see that he has anywhere near the experience that Bonehead has in support of that opinion.</p>
