for the 2nd-link, have you tried to download it ? last time I have a problem because I tried to download it .... problem is solved when I cleared all the cookies .... very good link, because you can see how to string the main using YY ES5Pro machine, and the stringer also used load-spreader .....
Yeah I noticed that too. Do you know if there is any place that sells such high quality base clamps? They don't have to be Yonex.
