I understand what you are saying. Thankfully I don't have that concern. My bottom is over 1 1/4 thick between the stringers and the strut block is about 12 X 12 single piece of machined billet, bedded, bolted, and glassed in.
I really can't give you an answer on what you should do. Will Andrews and Locks deal workout, I have no idea. I guess tell. If you are beating the thing like a rented mule it guess it can work with no problems.
I can only tell you that I can show you a number of places in my boat that prove the boat is twisting more than I would have ever imagined. And there is nothing light about my boat.

I see your reasoning, I just can't give you answer what you should do, other than ask if you think you really need to have a drop thru. Speed?
