From limit -> PL??

[wackjob]

What are the advantages of playing PL O8 vs limit?
I have been thinking about switching to PL, but since I am a limit SH HE player mainly, I tend to stick to SH limit.
When I play live, I play limit(kill).
Are the BR requirements different than NL/PL HE?
I multi-table and play mostly 10/20 limit HE, 2-4 tables at a time with a 5-10K BR. Would this be sufficient for a game like $400 PL O8?
