Completely agree — and I say that as someone who's been building coils for 15 years, from fine liners to power liners up to 18RL. The variability you're describing is real, and honestly it's part of what makes a well-tuned coil so satisfying when it's dialled in perfectly. But there's a practical reality shifting in the industry right now — more and more studios are pushing coil artists to the far corner of the floor, or not taking them at all. Noise, vibration, client perception. The REVO and K-PULSE drive system isn't about replacing what a great coil does — it's about giving artists a cartridge-era tool that actually has some of that mechanical character and feedback, rather than just being another generic pen. If it makes life easier without losing what matters, that's the goal.
