roger, excellent info in there!
i will have to call the place that has this sale on their website to see if i can choose the size of the boom as far as the package is concerned. the 'course' style boom is 182-244, but there is a 'formula' style that is 1 1/4" 223-285. i'll see if i can upgrade the upgrade. i dont mind paying the extra few bucks.
as far as the mast extension goes, rather than buy two, cant i just get the 48 cm and call it a day?
