I agree that comparable products can be purchased at a tack store, ebay
, etc. but be careful you know what you are looking for. Rope products that are made with polyester carriers and fill are MUCH better quality than ones made with polypropylene or other materials!
My tack is a mix of name brand and off brand(whatever I could get cheapest). The few non-polyester ropes I've gotten stuck with, turned stiff and scratchy in no time; they have a terrible feel both to the touch and in transferring energy. I also don't like to use a regular buggy whip or lounge whip anymore, the stiff "carrot" type stick is definitely a must to do NH properly.
PS to Lesandlily I love that web site you posted! I will be shopping with them soon.
