Large round/oval nets are often favoured by many lure anglers, for several reasons.
Being a mobile pursuit it's much easier to cart a round frame along a bank, (dragging if you will) by holding the net frame. Also the net frame leans against the leg nicely whilst actually fishing, no corners to get caught up in vegetation. Neither does it matter from which direction any fish are netted, front or side. If there is one down side, most of the round lure nets are none collapsible, but for my part, this small niggle is outweighed by the many advantages.
