Don't mind dropping Pittwater down to just the one spot, but do we keep east and west inlets for Stanley? Do we keep Montagu and Robbins Passage, as they are the same body of water as well? And what about Doran's and Mortimer Bay (just around the corner). Considering all of these spots, if the area can be described as a specific run, then I reckon it should be included. East Pittwater is quite an obvious and distinct spot to West Pittwater and doing a fast run at one does not mean you can do it at the other. There is no need to cull the list for speeds above 35 knots, as it's quite short anyway and the more runs, the more opportunities for people to try a few different spots to get a record, than just the 'fastest' ones.
I'd be more keen to include Muddy Creek and keep all of the others mentioned above.
Or, alternatively we cull all of those below 40!!
