We're just starting testing of a new type of line but one of the features will be safety marking of the lines. Often very dangerous situations are caused by simple switching front-to-back lines.
These simple tags can be shrunk on the ends of most popular lines with a hair dryer. More information is at:

Kite schools: these are free to you - just send an email (no scammers!). They're only $1. per set of 4 for individuals.
.....just wait 'till you see our new lines. No more limpies..no more stiffies! Later.
