Interesting. I consider the Bolt to be the disc for people who aren't quite ready for the stability of a Destiny. A spike hyzer bolt with height rolls over uncontrollably for me, whereas a Destiny slowly makes its way over to a roller.
I agree that the Bolt is definitely flippier than the Destiny.
Having thrown both, I just found the Destiny very angle sensitive where the Bolt (even though it's more understable) to be less sensitive to angles and thus easier to get good results consistently.
For full disclosure, I lack big distance but have a generally clean form and I do play at over 5,000 feet of elevation where everything flies a little more stable than you might think.
