Performer VS. Performer RPM

[IMPULSERACING]

I was wondering which upper intake do you guys think will be better for my application. The Edelbrock Performer or the Performer RPM. I know they say the RPM is for upper RPM over 5000 but it also says for Nitrous applications. I will be spraying a 150 shot with the possibility of 200-225. What do you guys think. Thanks in advance
P.S. I shift at 6000-6100.
