I have some advice i almost forgot to give out: Whatever kind of bag you use, practice with the OPPOSITE kind of bag for 1 month prior to worlds. That is, if you use sandbags normally, play with a 32 EXCLUSIVELY, and vice-versa.
I got screwed over last year in prague by having played 99% of the time with sand-bags, and having to use 32 pannel bags. I played like garbage the entire week because i was so unused to them, and it was a drag for me, so.....

Somewhere on Modified there's a post about ettique when recording videos, too.

very good advice. good thing you mentioned this.
I almost always shred with a 32, and then at a recent tournament I had to shred with a Mr. Sandbag during competition and it definitely was different from what im used to
