I know this sounds old but the best advise I can give Is "the search function Is your friend" It Is Indeed. I have never had to ask questions like this because I researched my subject. RWG has a Infomation data base that will give you all the Info you will likely ever need. I know It's easier to just ask but It's much more satisfying to find the infomation on your own,this is how we learn. To address your question,go with your gut and the good advice thats been provided,good luck
