He says he has calmed down, however. “It’s just from having a number of years playing at the top level. It is a technical sport but you also just need experience. We’re lucky in the front row where you can keep getting better the older you get. “Sometimes my focus has been lacking because it’s very easy to get carried away with the emotion of the game, especially at Test level where you’re playing in front of enormous crowds and playing the anthem at the start. It’s very easy to lose focus and not do the right thing at the right time. Over the years I’ve learned to stop getting carried away so much and just make sure I’m switched on at the right times.”

The relatively flat blades give good performance at those speeds, and excellent take-off performance, but I expected that they would run out of puff at higher speeds compared to the high-helix props like the Bollie and the Kool.  But testing shows this not to be the case, in that at the same manifold pressure settings, the Brolga performed at 86kts, within one knot of both the Warp and the Kool!  The pitch blocks only come in one degree steps.  16º is a bit too fine for cruise, giving WOT 6000rpm, but 17º is over-pitched for best take-off.  Since the Brolga is under-pitched, the rpm for the same manifold pressure setting is higher, but the speed was still the same......  I had expected that this large 4-blade prop would be best at take-off and noticeably slower at such speeds, but it seems not to be the case.......  At WOT it gave 100+ knots, same as all the others, which was really surprising!

The Prop Protector cut the rope cleanly, and all the netting. It didn’t shred the netting but cut through it, dividing it in two, and would prevent your boat being anchored by a long length. When the polytarp was left to drift into the prop, it tended to get caught on the blades and just swirled around, but as soon as a slight amount of tension was applied, it was cut through. However, it wasn’t shredded and sometimes remained on the blades, which would reduce thrust. In practice, a large sheet would possibly apply enough drag to make the cutter work. It couldn’t cut any of the wires, though. The netting and smaller diameter ropes could sometimes be drawn down into the gap between the cutter and the P-bracket but reversing tended to loosen this.
