Is it okay for Lua to just troll without hitting the front guide?

Yes. If you use nylon or carbon line as your main line, you don't need to use a leading line, but if you use PE braid, you can use a leading line according to your own situation. It is not mandatory to use a leading line for Lua, and the use of a leading line or not should be determined according to the specific situation.

The section of line that connects the lure (pin) to the main line and is 30-150cm in length is the leading line in a LUYA fishing set. The advantages of the leading line are as follows:

1. Protecting the main line: Avoiding the damage to the main line caused by the heating of the main line rubbing against the guide ring when it is pulled at the moment of casting.

2. Wear-resistant: After dragging the bait or hitting the fish, it protects the front end of the main line from cutting the obstacles.

3. Conceal the main line: Reduce the alertness of the fish when they find the line.

4. Cushioning: Counteracts the instantaneous pulling force that may occur after being hit by a fish and acts as a cushion.

5. Protect the rod: marking when retrieving the bait, preventing the bait from colliding with the rod's front guide ring and injuring people.

6. Favorable casting: The use of reliable, higher-than-mainline-strength front guides increases the possibility of experimenting with thinner mainline options, which makes casting easier and lets the lure fly a little farther.

7. Protection of personal safety: Lua hanging bottom is a common thing, if the use of PE braided line, hanging bottom can not be saved, can only be hard to pull, in case the line is strong enough, the hook breaks, this time the bait may be like bullets to the person pulling the line shot, if you use a nylon and carbon lead, such a situation can break the lead to protect the main line and personal safety.
