Dude GFY. I have been polite in my posts I even posted disclaimers such as "I am not bashing Tony just calling it as is.."I cant help you are retarded and dont comprehend.
Polite or not, the OP started by saying "this is what I have". Thus, the question of "why not got bigger" is null and void.
The OP has the parts, he wants to put them together, he doesn't care if there are better options because he has what he has, and bringing up those other options is pointless and only derails the thread.
