Just getting into quads?? Look to the used market for 2 sails - a full sail and a full vent. You will cover almost all the wind conditions with those 2. Unless you have plenty of cash to throw at a kite, you might not appreciate the differences. On a used kite you can get all the learning out of the way, then decide on your colors when you're ready to get the best! And be able to feel the advantages.
Get the 80-85' x 90# line set to learn on. Much shorter will cut down your wind window and make things happen fast, maybe too fast! Down the road, look into 120' x 90# lines if you want to fly with others, it's a standard length for teams. Then you can accumulate other sets, 50# for light winds, short 30' and/or 50' for tight spaces, etc.
Most beginners use a 3 wrap frame to learn on, strong enough to take the knocks, light enough to fly most winds. If you can replace a 2 wrap with the race, go ahead. It has a different flex and "snapback" than any of the regular wrap rods. Some like it, some don't, but it is a stronger, but still light alternative to a 2 wrap. A 4 wrap is nice to have for those really big wind days.
Having the 2 sails, 3 frames, and a decent set of lines will get you started.
PS: Thanks for the plug guys!!
