Rosewood's 160/80 injectors

[Firehunter]

Been looking at these for a while now. I had my heart and money set on AC's or stage ones but a recent thread pointed out that Jim charges the same amount for stock or 80% nozzles on these injectors. His website also states that he has worked with y'all (Bill. Cody?) quite a bit on the tuning. What is y'alls dealing with these injectors? I know FFD has the 160/100, is there really that much difference?

In the thread I referred to, it was stated that the 80% nozzle could actually run cooler EGT's while towing than the stock nozzle. True or ??

TIA.
