You can then coast down onto Channel & around the slight bend onto Lagoon (but you have a stoplight that might mess up a run) or you can turn a little bit more sharply onto basin and coast unimpeded:

Start from the same spot on the hill each time (e.g. a certain lamppost) and see how far you coast (either to a stop or until you drop below a certain speed).
thats a good idea. whats the speed limit? i know aero matters more at higher speeds. going slower probably wont show much of a diff like it does with low rolling resistance tires tested
