flared or round loc line nozzle

Simple question, not of much importance but just curious about the spead difference.. what do you like more, a flared 3 inch nozzle or a round 3/4 for the return ? spread wise and flow

reason i ask is because i need 4 nozzles.. i was think 2 of each but the site sells them in packs of 4 ..just looking for a second thought

 

the flare nozzle concentrates and spreads the flow way more, the round one does nothing, you may as well leave it with no head.

 

just get this.
Innovative Marine Spin Stream - Return Nozzle

 

Thanks thats the answer i was looking for.. i thought the same thing, a 3/4 nozzle looks basically like it would make no difference

 

i like the idea of that link, spin stream but at $30 bucks i can get a power head lol Thanks though
