Everyone loved that Sparco tape. But not at
$12-14 for a 6-pack.
I tried to find other tape that would do the job. If anyone has anything to add, please do.
So I went out to find other tape that was 2 mil and well reviewed. I failed. My comparison is below.
Presenting,
this tape.
It looks and feels, unwrapped, just like Sparco tape! I was so excited! It says it's 2 mil, Sparco is 2.1, not bad right? Great reviews and even better price! Initial comp below:
Sparco vs this tape:

From above:

Width is NEARLY the same. Which would make sense - 2 vs. 2.1 mil. Good sign so far!

Weight of 6 wrapped rolls also very close:

Unwrapping Sparco tape is a pain. The rolls don't separate easily and the plastic comes off in 8 pieces. Unwrapping this was super easy. Good sign too?
Single roll weight:

vs.


... And they even look the same in photos. Good transparency and decent adhesive. However, this tape is very thin and light feeling. It moves easily with wind and flexes too easily. Like, when you touch it, it sorta wraps around your finger, vs. the Sparco which will stay a little more straight. It's nearly impossible to explain without being in person. There is something about Sparco tape that has a certain amount of "rigidity" in addition to the stickiness. Maybe the rigid feel is created by its adhesive.
This tape, on the LEFT above, feels like those regular cheap rolls you get on any bulk ebay buy. I have probably 100 of them in a box from before I got tired of taping everything twice and switched to Sparco when everyone else did. I can still use this tape for some stuff, and for backup, but for now, I'll continue to work off my Sparco stash.
