I do not agree with you on what the tip costs. Sage rods are made in the US. Each rod touches about 40 pairs of hands. The tips start as sheet graphite and have to be rolled, sanded, a finish added, backed, guides placed and wrapped. Each piece is custom fit to the section that you send in. Warranties are time consuming and costly. if you add the material and labour, it cost the US rod companies far more than what you pay.
A rod tip that is made off shore can cost less as you stated, due to the labour costs. That is not the case with any major US rod company.
