Now, the most condensed shape of all is a ball, but a ball could possibly roll around before the full weight is felt and it isn’t tapered towards the back of the lead enough to stop the hook link tangling around it.
So, Dan chose to put four flat sides onto the ball and gently taper the back to avoid tangles. An appropriate name that summed up the lead, was, of course, the Square Pear.

As an inline, there is no lead out there that the fish will feel the full weight of more instantly. Even as a swivel lead, the fish will still feel more of the weight sooner because it's so short and one end of the lead is almost the same as the other. Only the movement of the swivel will make a difference.

So in short, you have the most condensed inline lead and swivel lead there can be, with flat sides that work in a fishing situation. We know because this is already the second generation of square pear, the first generation was too square which meant some times it wouldn't roll over and lie on its side; instead, it sat on its end with the swivel at the top of the lead sticking bolt upright off the lake bed, not ideal at all.

This lead will cast almost as far as a normal pear lead but will have better hooking potential so I recommend you use it everywhere you can. The only time to change is when it will not cast far enough, then it's time to change to a Skyliner for inlines or a Tournament or Swivel Distance for swivel type systems. To maximise distance use a swivel lead, as it will always cast further than an inline.
