I would go to a reputable Shimano dealer and ask him to try it out.
We have weights, drag scales and an assortment of test items ready for our rods. You can ask anybody who has come in to order a rod..... we make you try it before we take a dollar for a deposit.

If the dealer will not allow you to test a rod for its rated performance, then he is telling you that he does not trust it himself. That's just reality!
Shimano makes a great rod, but they are over rated in their performance numbers. If you want a rod rated at say 15-20, you should buy the rod that is rated 20-40. Otherwise Shimano has it down and they make a good product.
Thanks for the compliment on the custom rods. I understand what your saying, but Im sure Mike would agree when I say that although we cost a little more, you are getting MORE for your money. Your getting a rod built on the spline, a rod laid out for maximum performance, a longer lasting rod too. Take the looks out of it out of the decision, all together. Thats just for show.... . Your getting more bang for your buck with a custom rod from an experienced builder.
You can come in and lift weights in my shop with our rods. I would never stop you. Your also getting a higher resale value too. You just admitted that you can buy that $279 rod for under $100 with Shimano. Try to buy one of Mikes rods for that, or any good builder...... Im not trying to sway you at all. I'm using your veiw on a custom rod, to explain it better for those who feel the same way. A custom rod is not all about the looks. While its a great addition, its the last thing we think of as a builder. We build to perform first, look good second. Im not picking on you at all, please do not take it that way. Plenty of people feel the same as you do. Its always nice to explain it a bit more.
Anyway....... go to a dealer and ask them to prove the product. They should have no problem doing it. Unless, they dont trust it.
