What the thread found

• The Pro arm is considered a significant quality improvement over the 3a arm model
• A Pro 1 sled can be upgraded to HD specification through third-party modification
• The recommended upgrade path is to prioritize the arm first, then upgrade the sled later rather than replacing both simultaneously
• Basic sled performance foundations should be verified before investing in new equipment: the vest fit, gimbal stability, absence of vibrations, and solid top stage construction

Depends on

• Advice based on personal experience rather than comprehensive comparative testing
• Decision factors depend on individual priorities regarding HD capability and battery compatibility
• The upgrade path suggested assumes the existing sled is fundamentally sound
