For fishing 2-3 oz glides like the KGB Chad Chad or TSG, I would recommend using a line in the range of 16 to 25 pounds. The video suggests that 16 to 20 pounds would be ideal, as going up to 25 pounds might affect the bait's action. It's important to find a balance between strength and maintaining the desired action of the bait.
As for the gear ratio reel, the video mentions that a gear ratio anywhere from seven to eight would be suitable. However, it is also mentioned that a gear ratio of six can work, but you would need to provide more rod input to achieve the correct chop. So, a gear ratio of six can be used if that's what you have, but a gear ratio of seven to eight would be more optimal for this type of bait.
It's important to note that these recommendations are based on the video context provided. If you have any specific preferences or requirements, it would be helpful to provide more information so that I can tailor my answer to your needs.
