I have 3 of Lam's ABS kites - there are quality alternatives out there. You pays your money and you make YOUR choices - depending on what is the best for what you want to do. Although I'm not a free market capitalist (Canadian socialist by birth 8-) this is a small market for a luxury good where I think the 'market' will make it's wishes known fairly quickly. I think it will create a two or even three tiered market with levels for noobs, prosumers and competition level, with all of the really significant marketing happening by word of mouth and forums like this where the cognicenti hang out.
My two cents.
🇨🇦 HAPPY CANADA DAY!!! 🇨🇦
I don't know what you mean by "bold" line, but I had the Killip on a white 1/4" 1,100-lb line, with the fish kites/laundry run up it on a black 500-lb line. (I wish I had put the Killip on an 1,800-lb line because the winds rose from a little under 15 knots to more than 22, gusting to 24! The larger rope would have been much easier to handle when walking the kite down sideways on the narrow beach.)
For scale, the pink shark kite is 20' long, and the black fish (24' long kite) is only half way up the white line. Technically, the Killip is not lifting here, but providing a rock-steady taut line to keep my fish corralled on a crowded beach of flyers. The fish kites and laundry were difficult enough to pull down in the high winds without fighting the Killip at the same time.
