I have see the difference in the oil life after installing this brand. I'm not taking anything away from the rest as long as they are spraying any water it has to be better than nothing. So for the ease of installing and efficiency it just my choice of shower.
simrek's spray most water on the side and back of the case where the case is thinner and in contact with the lube inside. Those that just bounce some water off the top cap do not transfer near as much heat.
It sees it's air time as well, one thing to consider here tho I only run 3 & 4 bladed props I think sometimes this is overlooked when people want their Bravo's to last behind bigger power.
