I recently did not pass my level IV. I seem to fall into the category of a light and tall flat flyer that has trouble forming a good arch. I read a bunch of the emails for similar body types. It seems like tall thin people have trouble with an arch and sometimes need extra weight or trying a "Mantis" position. I would like to know if there are light and tall skydivers out there that are able to get into a good arch and any other tips to help me with my body position. I am also an older student (63) and not sure about the reality of trying to make my body more flexible. I'm trying though.
