Let's start at the beginning:
Let's start at the beginning: These are the only longe lines I don't hate. If you are nodding along with me, you probably also wonder why companies are making longe lines from cotton webbing that breaks in 2 months, or 50lbs 3" diameter rope???. In fact, these longe lines are so good, I give them out as gifts! I'm tired of seeing horses and people dragging around fat longe lines on the ground while working.
WHY THEY'RE GREAT
Perfect length for most arenas.
Lovely brass hardware that's easy to replace.
The right shape for your hands (nice, round, small diameter).
The tension is firm (no stretch).
The lines are smooth, but not slippery (in bare hands and with gloves too).
Easy to clean (just hose off)
Easy to dry (the synthetic fibers don't retain water).
All of these features make correcting undesirable longe line behaviors fast and simple.
WHAT'S NOT GREAT
Shipping time?! Honestly, I'm drawing a blank. That's why they get 5 stars. I love this product. I love Dura Tech products. They haven't let me down yet.
HACK: PERFECT LONG LINES
They are also the perfect length for long lining (on a circle, e. g. , traditional Spanish Riding School style). If you are passionate about self carriage, collection, poll flexion, etc - you know what I mean. The clips are too big and heavy for long lining but they are easy to swap out with smaller brass clips. I also have the DuraTech long lines (great too), but I keep them for ground driving outside because they are about 15ft longer.
