I also prefer Tie-Wraps for profile tank mounting.
The low profile version makes for a cleaner installation. The low profile routes the tag ends (pointed end) of the ties parallel to the main tie strap. The most popular wraps run the tag end through a perpendicular slot, and it sticks straight out into the air stream. That sharp edge of those clipped tag ends is also hard on skin when snagged.
Thomas & Betts handles the low profile, but I've not found them in other brands. Took me a while to locate a source, so you may have to search for them.
Of course, you all know that black wraps are better, as white, or natural colored ones get brittle in sun light.
