hey Ben !
yup, by looking at the rod/line proportions it's already quite obvious that it's a very, very short line
(that's from Rio's spey chart btw)
sure, there's too many variables: kit, caster abilities, conditions etc, etc to establish absolutes but my point was to simply show the part of the line we're using to 'load the rod' and to differentiate it from the anchor. yes, it's a rough drawing but for that purpose the drawing works well.
cheers,
