Last night I learned my lesson on the speed of the music dictating the style of spinning... I'd recently been playing with shorter and lighter poi (which, of course, spin much faster) mostly to techno speed music.
I lit up to a slowish song and felt like a fish out of water. Having to slow down to keep the beat of the music was next to impossible with short chains. I kept loosing momentum at the top of my arc and even choked for a second on a wrap that was far too slow. (Kutos to Adam for the leather welding sleeve advice, saved my arm dude!) My short, light poi simply refused to slow down in the style I was used to spinning. Yeah, I could have gone off the beat but I like to play with the music when I spin. Later I spun with faster music much more in resonance with the length and weight of my poi. HUGE difference. I had a blast.
Yeah, yeah... I should learn how to lengthen and shorten my chains on the fly (on my list of things to do after: Behind the back weave and butterfly alternating arm wraps.)
The real moral of the story for ME was: If you don't feel the music, don't light up.
