Here's a good explanation & comparison of hybrids to 160's.
Serious 7.3L Power Stroke Upgrades - Diesel Power Magazine
I've towed our 5th wheel with Swamps 175/146 (stock nozzles) injectors for about 10 years. They have been great injectors. Being single shots I was able to still use the stock HPOP and maintain 3100 psi when the tune calls for it, plus a small bump in MPG's. but without the Van Turbo and DI intercooler I would have had to back off the throttle towing on higher grades at lower rpm's to keep the EGT's in check on some of the tunes.
Towing with 160/80's has been good as well, but it's all in the tuning. If you don't want to deal with the time it can take to dial in 100% nozzles then 80% nozzles are the way to go. Much easier to tune for. Well, it's all much easier now that you can receive tunes via e-mail. A few years ago we all just waited impatiently for the UPS truck to show up.....
Hybrid 238/80's would be the next I would consider putting in the F-250. For towing, they look great.
But again, it's all in the tuning. You don't want to run 450 hp towing, you'll brake stuff - expensive stuff. Towing tunes that keep it in the 350-400hp range are the way to go........Then if you have a PMR's you need to adjust for that as well.
Here's another good article......

Injectors are in my sig, daily driving, the PHP custom 80hp tune is great fun and too tempting to keep MPG in check so I also use the 65hp tune. when it comes to towing, I go straight to the 25hp tune (heaviest tune offered by PHP) and then I don't worry about EGT or MPG and still have plenty of towing power.
