2. The main difference between the micro-wheel and the universal wheel is that the tension required by the micro-wheel to start the silk cup is smaller, the resistance of the silk cup is smaller when starting, the inertia of the silk cup is smaller when rotating, and the ultimate strength of its own material and shape is slightly worse. The inertia of universal wheel cup is bigger and stronger than that of micro wheel cup.
3. The micro-rods and wheels here refer to the gun rods and drip wheels that catch small fish and use light bait (such as white stripes, bass and trout). Fishing small fish with reed buds used to be the patent of straight handle pole and spinning wheel. Because the outgoing line is a linear wheel, it is difficult to throw light bait from 1 to 3g, so it is mainly used to throw heavy bait to catch big fish.
