Interesting to learn about the lead weighting of the staff on the Spey... is it weighted just in the rubber foot or throughout the staff? I see how weighting the staff allows it to behave more in the current.
Staff handling while fishing was always a little bit of a nuisance for me, but Tyler Kushnir of British Columbia showed me a pretty neat trick. The staff is on a tether rope, attached to the belt. The rope is set to a length such that the staff can be thrown over the shoulder, hanging behind you neatly and out of the way. To continue wading, simply pull the staff to the front using the rope attached to the belt.
