What are the key differences between trad climbing and lead climbing, and how do they impact a climber's experience and skill development?

Trad climbing involves placing removable protection as you climb, while lead climbing involves clipping into pre-placed bolts or anchors. Trad climbing requires more gear and technical skills, while lead climbing focuses on movement and route finding. Trad climbing can enhance a climber's problem-solving abilities and gear placement skills, while lead climbing can improve a climber's endurance and mental focus. Both styles offer unique challenges and opportunities for skill development in different aspects of climbing.
