It still amazes me that "most" the people with all the experience can't give constructive criticism. Rather than give advice such as @UsAmpsFreak did. Once you give you "constructive criticism" what the OP want to do from there is on him. Don't take it the wrong way just cause they didn't do it exactly like you did. If they have the money, time, etc to do it the way they want to, just sit back and see what the outcome is. If they fail then the "I told you so's" are in order. Otherwise there's no reason to come off as a Dick and keep pushing the issue just cause it's not how YOU would do it. Let them fail & learn. Tons of experience mean nothing when you look & sound like a total Ass.
