A back lead pins your line to the bottom between rod and rig, and while it solves a specific problem well, it is not something every session or every swim actually needs.
What a Back Lead Does
By sinking the line close to the bank rather than letting it hang through the water, a back lead reduces line bites from passing fish, keeps a line out of the way of other anglers’ tackle in a busy swim, and can help present a rig without a length of line silhouetted across a clear, shallow area.
Standard Versus Flying
A standard back lead is fixed onto the line and stays in place for the session, sinking a set section close to the rod. A flying back lead runs freely on a length of line clipped near the rod and can slide down towards the rig on the take, reducing resistance felt by a taking fish compared with a fixed back lead.
When They Help
Back leads earn their place on waters with heavy angling pressure and frequent line bites, in shallow or clear swims where a visible line risks spooking fish, and in busy swims where keeping a line low and out of the way avoids tangling with neighbouring anglers.
When They Cost Bites
In swims with significant weed, snags or an uneven, debris-strewn bottom between rod and rig, a back lead can create an additional point of resistance or entanglement that costs more bites than it saves. On clean, open swims with little angling pressure, a back lead often solves a problem that was not there to begin with.
Setting Up
Positioning a back lead a rod length or two out from the bank, checking the exact spot is free of undue snags, and using a flying design where minimal resistance to a taking fish matters most all improve how well a back lead performs once cast.
Weed and Snags
Before committing to a back lead on a swim, checking the ground between rod and rig with a feature-finding cast avoids pinning a line into weed or snags where it could become a liability rather than a help during a fight.
Alternatives
Fishing a sunk mainline through careful rod angle and tip positioning, or simply accepting occasional line bites on waters where they are infrequent, are both reasonable alternatives to a back lead where the specific problems it solves are not significant issues on the water being fished.

He is straight about which kit he has actually fished and which he has assessed on specification, and says so on the page.
