First things first, the question says "assuming I can carry my 265 into a severe headwind..." I cannot. So, in real life, I'd probably hit driver into the headwind, it looks like I'd be plenty short of any trouble. If I had no wind or a tailwind then the question gets a lot more interesting for me.
Okay, back to the question, if I "could" hit my driver that far. I would go for the green. Why? Because being able to hit my driver that far would go to my head and I'd be trying to reach any and every par 4 in one that I even remotely thought I could.
Incidentally, I've hit a number of Par-4's in one in my life. It's getting rarer and rarer, so I'm going to try it when ever the opportunity presents itself.
Why refrain from posting the updated grip and continuing to work on it until it is OBJECTIVELY good? I've noticed that people that grip the club poorly in the first place tend to not be the greatest at realizing when an "updated" grip is still bad or they just fiddle around at address until it is right back in the same poor position.
Also, golf swing and grip changes shouldn't necessarily be comfortable. By settling back into a grip that feels comfortable, I'd wager it's likely not very good.
