Eh..............well.
I play Thunderbirds and own lots of them from many different builders including Epiphone, BaCH, Ibanez, Greco, Orville, Gibson,Jackson and Lull, honestly I wouldn't use these basses if the OP's premise were true for me - It's not.
I mind my strap length, but don't use anything special, play mostly rock and pop in cover band so I work the money frets, I watch my weight, no beer gut to make my basses hang funny, been doing it for better than 30 years.........
Several other have made some well reasoned posts that state it pretty well, what works for one may not for another, nice that we can all be different yet still enjoy playing the bass.
I'm sorry but that is the biggest load of self-serving rubbish I ever heard! "Lets all have diversity and still get along! You sound like a democrat! I"m sorry neck dive is about the balance of an instrument. You know like those things that the statue of "justice" with the blindfold is holding? Generally speaking the end of the strap needs to be somewhere out near the 12th fret to get a balance on most basses. A T-bird is the WORST possible design with the lower horn sticking out (where the strap does NOT connect) and the upper horn recessed way in so more than half the bass is hanging off the end of the strap.
And I don't care how young you are, how flat your six pack, how thin your are, or how much you are imagining how cool you look, you WON'T be changing the balance of the bass by any of those wishful thinking things!
And the icing on the cake is your photo show a T-bird player (you?) with the strap tied to the headstock!!!! Well there's no doubt that this arrangement suddenly cures the "balance" of the bass! One of the other photos in the thread is interesting too in that it puts the strap on the lower horn. Gets it out at a good balance point, but does nothing to keep the bass falling forward with a twist! So just put BOTH your strap ends on the rear button of the bass and come back and tell us how your lack of beer belly kept it from having neck dive. (yep, got a beer belly and proud of it!) I hate neck dive.
