What have I learned?
I overpaid for the wrap. I was entirely too worried about the "precut" sizes, to make the job easier. In truth, they don't fit well, and probably will need to be trimmed on at least 3 of my 6 drums.
The tape method is bullshit. Easier, yes, but I am not satisfied with how the larger drums are coming out. The wrap is tight around the body of the drum, but not against the edge, which may lead to problems with tuning. Since the tape is only on the very end of each piece of wrap, there is nothing to secure the edges to the drum. Disappointing.
I went with the tape because I didn't want the permanence of glue. I was thinking of rewrapping them in the future, blah blah blah. Given the expense and effort involved, I now know that was ridiculous. This is it. For what I paid for the privilege of flexibility, I could have had the job professionally done.
Now my heads don't fit anymore. Specifically, the 8 and 10 inch toms are fine, the 13 inch is tight, but the 12 inch tom no longer accepts Remo or Aquarian heads. Evans appear to fit just fine, but I play Remo Ebony Pinstripe. This sucks.
Is there a bright side?
Sure. They look spectacular. Really, really good, which was kind of the whole point here. I am just disappointed in the process. Mainly because I paid so much. This stuff is very expensive. Given the money involved, I know now that I should have paid a professional to do it, and then I wouldn't have had these problems. At a minimum, I should have sucked it up and used the glue method on the larger drums (I may yet). I will start replacing the hardware tomorrow, so I should know the final result by Sunday.
Not sure yet what I will do if all this ends with my drums being beautiful, but unplayable...
