Assuming 5 steps of PB with DK>Twin>Demo immediately prior:
Boot > Boot > Boot > DK > Snap
225 > 225 > 225 > 150 > 180 = 1005 potency (before multipliers) using Boot's 100% crit. Then Boot/DK>Twin> Demo to get back in rotation.
The only way for True to pull ahead of Boot is if you crit at least two of them:
190 > 285 > 285 > 150 > 180 = 1090
You're probably going to PB with Internal Release up, so it's worth the gambit. Even if just one True crits, the difference of 3x Boots is a mere 10 potency and you stand to deal much more.
tl:dr if you're a bad enough dude to burn PB for raw DPS, do it: a) after a fresh DK/Twin/Demo rotation, b) with Internal Release up, c) True>True>True>DK>Snap
