If that is a Moen kitchen faucet, I will eat my dirtiest hat. My dirtiest hat must weigh 5 pounds, most of it dirt.
If I really don't have a clue as to the proper answer to the question asked (this thread being a prime example), I try not to post an answer.
Reason being, and I am speaking only for myself here, when I am extremely busy with day job and side business and family concerns, I tend to ignore the questions/threads that already have a member whose abilities I have come to trust participating. So, if time is short, I will bypass threads that Caduceus, JohnJH20, CamaroDerrick, or the like is posting to, and seek out the unanswered questions where I might be able to offer an informed opinion instead of just agreeing with another professional.
It seems that to me that other pro members tend to do the same, so I don't answer questions that I don't have a good answer for to someone else who hopefully does.
