I think it could be a neat technology. Definitely a bit pricey at the moment. Other concerns would be the speed of the whole process and the line size limitations. Not many folks are throwing flouro that small. If you are, you are probably not too worried about hooking a giant and getting broke off. Lastly, I'm assuming the weld is ridged. How does that impact the action of the lure? Particularly in soft plastics? Every time something new comes out people will have a million reasons why it's not needed. Only time will tell whether they are valid.
