Lisdexamfetamine vs. D-Amp salt combo - Preferences?

Anybody found they prefer one over the other, or mix and match for different effects? I've found that the conventional salt combo is a great immediate kick, and 70mg Lisdexamfetamine 2 hours afterwards not only extends the effects but helps diminish the feeling of the dexamp comedown. Fewer physical symptoms, too.

Also, any differences in the onset of Amphetamine Psychosis between either one?

Dude, I hate the come down, I'd actually get smashed more often but I really crash hard. Its cool how you found a way to lessen that negative effect.

Psychosis only happens to junkies. Did you see the end of season 5 of Dr House?

I did not. But I'm already on the edge of psychosis; been addicted to amphetamines for about 7 years now, and I'm going through anywhere between 10 and 15 30mg adderall IR's a day. Last week, between my nose and what I ate, I went through 52 in 2 and a half days.

So yeah, psychosis is a big concern for me.
