The bottom line is - no company is ever going to pay you more than 50-60%. So you only have the chance to make _less_ money on PPS, not more.
"Well let's see here, we did some number crunching and it appears your trials aren't converting well enough for our you-are-a-dumb-faggot PPS program, therefore we have converted you to revshare. Thanks for your business."
Edit:
BUT - if your trials convert like a motherfucker into long rebilling members - companies will be happy to pay you your measily 35$ PPS beer money to take your year long rebilling conversions
