Here are my recommendations: Oggz are expensive and not made well enough (especially recently). Home of Poi has an alternative
glow ball which are made well, from my experience. They're very durable, have good weight and produce a nice glow. Beyond this, they're pretty cheap, so if they do break, it's much easier to replace them without breaking the bank. As far as sock poi go....I have a set of
foxy sock poi which I like....if you get certain colors, they glow under the blacklight and you can also put LED's inside them. The jailhouse poi are pretty stretchy and I didn't really like the feel of the ones I played with. I don't know how the
cone poi are, but they look nice....you can also get them with ball handles which would be good for tosses. Beyond that, I really like my flowpoi....I have duos, but they might be a bit heavy and menacing for your first poi set....but whatever you think looks best. The trails they create are amazing and they are definitely an eye-grabber.
Good luck in your decision....also, if you're interested in a 15% discount code for HOP, please PM me.
