I don't have the Gator Bite. But have used the Sally's clip...... Same idea. And it works. Alot cheaper. I think it helps alot and makes it alot faster. But I learned first by using my fingers..... and believe me I had a few choice works before I finally got it. I think you really should learn to do your creasing by hand and then you can take short cuts if you want. I know alot of the time now..... I don't think my bows are as good than when I creased by hand. And I used wire to tie them off.
But what ever works for you is what you should do.
