Easy Tiger...I'm personally not looking to jump on you (at least not in the verbal sense, possibly in the literal sense, you're not a bad looking fella, lol.), but you did present the surface area thing as fact the way you worded it, and even if it's just a personal opinion, the manufacturer's documentation disagrees. That quote I pasted above is from Acme's site. So here is a fact, Acme's three blade props have an surface area EQUAL to their four blade, end of discussion. That aspect is not open for debate unless the manufacturer themselves are lying.
I did clearly point out that you opinion has given me food for thought based on your experience with a four blade, so don't get all huffy as I meant no disrespect. Just trying to get some clarity on the pros and cons and I do realise that the best place to get advice is straight from the manufacturer, but I do care what others think about the props they actually have with regards to real world performance.
Look at it this way, maybe by debating these issues we can actually present some solid factual info to future question posers...
Cheers
