I don't know if it's just me, but a lot of people around here, really don't like it when I fly near them. I often like to follow close behind people while the jog along the side walk, but I have had many times where the person grabs the kite and throws it away with a very upset look on their face. They need to lighten up.
Spence it might be the fact that your young, they probably get the impression you're being a punk you how people can stereotype without thinking.
Most of my Rev flying involves interaction with people, where I fly has a bike/walking path around the whole area and some actually get mad if I don't mess with them. One gentleman in his 70's will not pass unless I tipland on his hand multiple times
Once they get used to you it will change people have seen me playing with others and the next time they come by they expect me to mess with them, some days I can't even fly on my own it's spent interacting with passer by's Little kids are my favorite to mess with I can run them ragged all day and never stop laughing.
Then there are the dogs that love to hate my Rev but out of respect for antmans still healing wounds I won't go there.
One thing I did to all my B's was on the bottom pigtail I tied a knot between the standard and the bridle knot, that adds a bit extra. Another thing you can do and I tell this to all new flyers, on the bottoms of the handles make a knot 1/2" away from the ring cut off the rest burn the end.
Closer to the bottom = more brake again, then all you have to worry about adjusting is the top lines which makes life less confusing instead of having to adjust 4 lines.
Don't be afraid to let the bottoms of the handles swing way fwd, most people grip the handles like they are holding on for dear life squeezing will just make the kite come down and get you frustrated.
That alone gives my kite so much brake at times I have to give the top lines a quick tug to get it air born, but again thats allowing the bottoms to swing right up.
In time you will get your own feel and handle hold but the best advice is relax on the grip your not jumping the grand canyon.
Hope that helps, Oh and if you like don't cut off the excess bottom tag end until you have tried it and like the results, It works for me and may not for others but if you do think about it adjusting 2 lines does make a little more sense then fumbling with 4.
