Story
Choosing between going more technical or going more graffiti can determine how you could take on each level more effectively. By going more technical, certain levels like Benten Boogie or almost all of the Chapter 3 levels can only be beaten with a JET rating by spending a couple of minutes pulling off tricks/grinds in a designated area before heading back to spraying graffiti regardless if it's required or optional. I personally choose the technical route of playing because despite a higher point value the higher the character's graffiti stats are, they tend to carry less paint cans in total (except certain non-story-obtained characters) and I still mess up on mid and big tagging sections (which can cost some major points in total).

Challenge
-By knowing where the paint cans will be in a Jet Crush challenge level, it makes these so-called "races" a bit easier if you can already skate pass the CPU. It's especially effective in Grind Square, for example, so you don't have to follow the CPU's path almost entirely.

-In a Jet Technique challenge level, its way more effective to just find a grind loop and just go to town from there instead of going/finding green tags to graffiti on. If they just so happen to be where you're pulling off tricks/grinds and you have a can or two at the ready, then spray away; otherwise, just stick to pulling off 15+ trick/grind combos until time runs out.

-Only the Jet Graffiti challenge levels require actual graffiti tagging outside of a simple stamp of a small tag. For me, since I played more technical, I kept, at least, one tag near a potential grind loop unsprayed and waited until there was less than a minute left to spray it, using up the remaining time to just pulling off tricks and add more points to my overall score.
