Re: hi-hat stand recommendations?
The Yamaha 740. I know you said you didn't think they've been putting their best foot forward, but this stand seems to have everything you desire.
The legs swivel and the tension is super easy to adjust. It is single braced, but has proven very durable for me (been set up/broken down at least 50-60 times with no problems). I'll bet you'd love it!!!
Practice, Improve, Repeat...
