First Rev - a full sail (std), and keep an eye open for a full vent (f/v) as soon as you can! Nothing more frustrating than going to the field and not enough wind for the only thing you own!
Why my suggestion? Think of laying bricks - the 1st row is laid end to end, then the 2nd overlaps the joints. Pretty much how Revs work. There's enough overlap in the 2 sails to get you by. A mid (IMHO) is great for the sweet spot it fills, but is not a good first choice, unless you just have the winds all the time to use it! And please throw out the stated wind ranges! Fly in too strong a wind and you stretch the sail, never to return to what it was before! Therefore the 2 sail idea!
Try to hook up with others first - the experience shaves light years off your learning curve!! Try some of their kites to get a feel for what you like!
Frames: For starters, use the 3 wrap (marked with 3 feathers on label or UL) or the green race frame - both are pretty tough and will take most of the abuse you'll dish out to start. Then either the 2 wrap (2 feathers or Pro Use Only) or Black Race when you get past the stage of unexpected impacts! PS: all the 1.5 frames are interchangeable in any 1.5 sail!
Lines: the 80-85' lines that come with it are a good start, long enough to have some room, short enough to fit in most places. IF you plan on flying with others - 120' lines fill the bill - bigger wind window and more space for a team.
Handles: If you get a "B" or NYM - throw out the top leaders and make your own - much longer! A good guide is long enough to reach across the gap, bottom leader to top leader. Here's a link - http://www.revkites.com/forum/topic/4409-my-leaders-your-thoughts/ . Some pix that show things! PS: join the Rev forum too, lots of info over there on these kites!
Equalize your lines!! Before you ever put a kite on them - stretch them out and check that they are even!! Uneven lines means you let the kite go wherever it wants, even let you take control!
Single biggest piece of flying advice - learn this saying - GIVE TO THE KITE!! If it's gonna crash - LET IT! Better to go straighten it out than get down there and find something broken! Pulling only drives the kite harder into the ground!! GIVE!!!
OK - end of book!! Good flying!!
