pinwheel vs needlewheel

[Workaholic]

Well, when you have the option for either is it going to make a difference to spend the extra $$ to get the pinwheel or is it not worth it? My particular scenario is on a rio 1100 pump that is attached to my cpr backpak, its in need of a new impeller and I have the option of a pinwheel or a needlewheel impeller. what do you all th ink?

Thanks,
Tom

Tom, the pw pulls more air and makes smaller bubbles. But on a rio its not going to make a huge difference. But i'd get the PW.

Acording to Klaus, BK's owner metal pins charge the bubbles more that they stick more DOC.
