Best stunt kite line

Start here: Prism 90 lb × 65 ft Spectra set. Prism is the name most stunt-kite flyers trust, and this is the classic dual-line setup: two matched braided Dyneema lines, flight straps and a winder in one box. Low stretch, so the kite answers your hands instead of sponging, and 90 lb is the sweet spot for most beginner-to-intermediate dual-line kites in light-to-moderate wind.

Who the others suit:

• Bigger kites or stronger wind: the 200 lb × 80 ft Dyneema set — more pull capacity and a bit more room to fly.
• Very large kites or gusty coastal air: the 353 lb × 98 ft set; heavy, but it won't be the weak link.
• Small, light kites and kids: the 50 lb × 65 ft Prism set — thinner and lighter, so small kites still respond.
• Budget first set: In the Breeze 50 lb × 80 ft, or their 100 lb version if you fly a mid-size kite.
• Building your own lines: Climax Protec spools, pre-stretched and abrasion-resistant, sold by strength.

Match line strength to the kite, not to the wind you hope for — too heavy a line makes a small kite sluggish.
