Xnr,
I am not sure what you mean by a "bull" answer. What did they say?
The rules that you fly under are part of your ops manual. I assume you are a 135 operator or its equivilent. Does this manual list the helipads and procedures that you are authorized to use? If so, you are covered. If not, then how are you authorized to land there?
Every now and then someone with too much time on their hands comes across an inconsistency that seems overpowering. A few years ago a NY city pilot discovered that if he landed at a helipad in Manhatten, he might actually be violating the flight manual HV curve for some obscure reason. This made its way around and around, and was never really resolved, but folks kept operating, and eventually it was forgotten.
Nobody will publicly advocate breaking any rules, especially TC, and neither can your management. If you ask a question that requires them to assume your risk, or that tells them to stop your operations, you will not get a yes or no answer, because they're not that dumb.
There are Cat A procedures for every transport helo, of course. If you must use them at your heliport, and the heliport is too small (or the procedure needs too much room) then you should find a new place, or a new helo, a new job or a new hobby to keep you occupied.
