Please could anyone point me in the right direction with regards to leader construction as to a general rule of thumb for various stillwater and river leader make ups? Or point me to a webpage that explains it.
Thanks

The leader butt attaches directly to the fly line and must be of a diameter similar to the end of the fly line to transfer energy from the fly line to the rest of the leader smoothly. The graduated mid-section transfers the energy from the butt section to the leader's tippet. The butt and mid-section are designed as a delivery system for the tippet and fly. The tippet is the leader's single most important component. The tippet size and type are determined by the fish and fishing conditions. Commercially made knotless tapered fly leaders are alright for many applications but for some situations it is better to make your own leaders by knotting together sections of monofilament and/or fluorocarbon.

Generally speaking leaders that are made for delivering a fly with authority are 60% butt, 20% mid-section and 20% tippet. Leaders that are designed for soft presentations or to combat drag have shorter butts and have longer mid-sections and tippets.
