Going from asset management 600B firm to small PE Advisory Firm--am I crazy?

Hi All, So I'd like to go into the PE industry but can't seem to break-in with only my buy side –fixed income-- asset management experience. I have however received a job offer at a small (less than 30 person) and around 20-25mm rev/year and fast growing advisory firm to large institutional PE money. Would I be crazy to accept 20% lower pay and become a senior type analyst for a small PE advisory firm? At the new job I would be dedicated to one client, a top 3 U.S. pension fund in their PE group. I'm late 20’s, married, no kids. I'm thinking it's now or never and 20% isn't that bad considering the experience I’d get. Does anyone know what the going rate is for a 2-4 year analyst at a firm like this?

Also, I keep thinking about how my current job is relatively laid back with not a whole lot of work to do. I’ll probably end up making bank at some point if I just “hang around”, but I’m really sick of fixed income and the lazy/un-motivated culture is starting to annoy me. You buy side guys, am I crazy to leave this “cush” environment?
