Is anybody using these props with a 1:1 transmission and an older carbed boat? I'm wondering if the OJ is worth the extra money? I know these are the recommended props from each manufacturer as I've spoken to them already. The OJ really doesn't have a lot of info available and the acme is either the best thing since sliced bread or is commented as being over hyped with thin blades. With both manufacturers being the top choices, I imagine they are both quality products and the negative comments are unfounded. Can anybody offer some more insight?
