Well I tried them and here's my thoughts.
Thin 1" is 11"
Thick 1" is 8.5"
Thin 3/4" is 6.25" (I guessed here with a piece of paper to test, my guess was 7.25" and I had to cut an inch)
It got progressively harder to install as I went down... 3/4" was an utter pain.
What I was hoping for was a softer core and better evenness like my dual tube. I got a little of both I'd say and I'm satisfied... I kind of wanted a closer look to Erv's blades which uses the great half of both types of films.
Counter intuatively the smaller ones benefited the most. The Thin 1" to me didn't gain nearly as much evenness as the others. While 1" thick and the 3/4" thin were noticably better.
My final verdict would be that if you are looking for a softer core and more evenness in the smaller ones, go for it! Pics will come. I have to make my next two blades.
