what came in mind recently.....
what is the definition of a beginner/newbie??!!
some just want to fly straight lines and corners etc....
some are more eager and want to become really good....
all starters have to begin somewere....
while typing this...i forgot actually what is my point here

i think it's up to the beginner asking themselves....what he or she want to achieve....
if your goal to be good and better ( eager/competitive attitude ) and starting into competition level flying, even if your level is not even close to other competitors
start with good basic material and longer ( than average ) lines, for upscaling your skill level in less time, than playing on your local field learning yourself.... fly with others, ask them all you want to know and driving fellow kiters '' crazy ''

if your goal is, flying kites will be fun and a nice free time hobby and you are less competitive orientated personality....choice is still '' free '' what material suits with your preference/ finance etc....
i would suggest pick a decent allround kite ( not too small ) and pick some shorter lines, it benefits your achieved '' fun-factor ''
this is just a point of view, not a judgement of right or wrong....
maybe you can resume all this, by asking as a newbie into kiting yourself 2 things: what kind of beginner am i and what will be my goal to achieve??
Good points Martijn. I think that is kind of covered under the when should i upgrade section. The beginer this should stay gear toward though is the new flyer that may have tried a few flights and is looking to get their first kite or the flyer that has a cheapie (el crappo)and would like to step in to a good starting kite but is still learning to get off the ground. THe more new fliers that get started with good equipment the more that will get hooked

I've taken quite a few that have crap kites that made them frustrated and ready to give up, handed them one of my kites and created a new addictee.
