Hi Nick, congrats on the win! To further expand on Scott's post above me, I will add: If you can afford to own multiple kites, start with the EXP. You'll outgrow it one day, sure, but you'll undoubtedly come across onlookers that ask, "Hey, can I try that?" With your old EXP kicking around in the kite bag, you've got a rough-and-tumble tutor ready to go at a moment's notice as you fly your new B Series along side them showing them what it should look like when it's working.
The only thing better than kite flying, is kite flying with friends!
