Which 5.5?

[sime46]

I need a new 5.5 for my 4wd(bmax). Was thinking of either a speed passion v2.0 or maybe a Novak ballistic. Does anyone have experience or opinions on these or could reccomend a viable alternative? I'm after something relatively smooth on delivery but with good top speed. I've been using a 7.5 X12, but with this car I could use more power. Thanks for any help you can give. These things aren't cheap so any info or advice is gratefully received.
