When people ask for recommendations I make recommendations based on what I feel is going to help the customer, and work best on his combination. Sorry you don't feel that is correct, but it's much better to try and give a person the proper technical information based on how a product is designed and manufactured rather than have them spend their money on a part that is not going to work properly.
I do not try to sell, anything to anybody. Just making product recommendations to help. This is something that any manufacture could do if they wanted to on a site like this if they wanted to take the time like we do.
