Well, I got my samples from both Hydro-Turf and Black Tip today. In my opinion the Hydro-turf feels and looks to be slightly better in quality, although Black Tip is not far off.
All three Hydro-turf samples, 2 solid colors and a multi color sample, were identical except for color.
The Black Tip samples, 3 of them, were all inconsistent in thickness, size of the channels, and hardness. Still, if they had the color I wanted, I may have bought the Black tips as the price includes the adhesive (peel and stick).
I too requested samples from both Hydro Turf and Black Tip and have received and tested/compared both...
I actually measured thickness of both products, in several locations of each piece and measured each piece that I received.
My findings were that the Black Tip product was actually THICKER than the Hydro Turf, that said the Black Tip was sent with the PSA backing (Which I think was GREAT as it gave me a chance to actually try it out and see if I like it), also the Black Tip samples were about 4x the size of the Hydro Turf samples. As far as consistency both had about the same consistancy of thickness.
Quality wise I can't tell any difference. I squeezed them both to see their density and they feel about equal. The groves in the Black Tip product seem to be a tiny bit wider and a tiny bit deeper then the Hydro Turf product. I checked the width's and they were consistant.
As noted the black tip samples came with groves cut in different directions from each other, but that is probably just due to cutting samples out of different pieces of scrap and doesn't really mean anything... If the samples are cut from the end of a piece or a corner of a piece I could see where there might be some differences no matter which manufacture it came from.
I must say that I like the PSA backing of the Black Tip; I really wish Hydro Turf would send their product with the PSA backing as well to make a comparison. I think they would probably sell more with the PSA backing if they did.
One more notable comparison is that the colors from Black Tip and Hydro Turf are completely different from each other, which means you may have to choose 1 brand other the other for no other reason than the color.
The blue from Black Tip actually matches my ski 100x better than the blue from Hydro Turf, so I am likely to end up going with the Black Tip for if no other reason, the color matches my ski.
My opinion on this is that without having tried either product, both products are of equal quality, most likely you will end up with 1 brand over the other based on the color alone but if you find an appropriate color from both companies and are trying to decide which one to buy, I say save the $$ and buy the Black Tip.
I think I will end up buying Black Tip for my ski and Hydro Turf for my wife's ski due to the colors available from each, This will also allow me to directly compare both of their products with the PSA backing and make a 100% 1 to 1 comparison between the two, but I'm really expecting not to find much difference.
