Tails are good for slowing kite down on a windy day, plus fun to do figure eights and corkscrews and infinty loops!!
If its not that windy try a flat tail- they don't slow the kite down as much as a tube/tail in any case i's go with a 100' tail
I did the five section tail thing. didn't like it. ended up buying a flat/tail to color match a couple of my kites.
So if your interested in taking my huge tail off my hands- its two 25' black/white tube tails, two more black/white tubes but the srtiping is a little longer, then a red/white/blue tube. All in all 100' + in tube tailage. Lemme know. i bought Premier, and Gomberg and NewTech tails if memory serves.
PS on the beach be carfule with your tubes cuz they'll pick up sand!!!
