Re: Top section I sail on the East Coast in Australia and have been testing these masts. I tried one out one in about 25-30 knots last weekend. I could not tell an ounce of difference in performance an my results for the day pretty much backed that up. However, what was different was when I came ashore after a day of extreme vanbging my carbon top section was (of course) perferctly straight. The same could not be said of an aluminium one. One quick note anbout trying to make the playing field level by having all of the same equipment. I weighed four of the carbon masts - and guess what... not one was the same weight. I cnanot understand why, more fibre? More resin??? Obvioulds this would result in slightly stiffer/bendy top sections.
