oooh, I love honey crunch--it IS aptly named though--they got the "crunch" right--it's shocky, shocky, shocky, but the color is worth it!
The devardi, if you don't pre-heat it (I don't) does best if you treat it as "shocky" (some is, some isn't) & do the "bounce, bounce, bounce" thing in the flame first, & then expect it might shock off the rod a bit...if you melt it "further out" it's easier to control & keep it so when it does crack, you can keep it melting the rod on if you're doing a bigger bead, or just spin the piece on & break it off the rod if you're about where you want to be when it happens.
I pretty much treat all glass to the bounce-bounce-bounce anyway, it's a habit I haven't lost yet from when I was hotheading out in the driveway
