Break in

I've been working at a mid-sized investment consulting firm since undergrad (graduated May 2006), and I want to move to a fund. I was promoted at the beginning of 2008 (20% raise), and passed the level 3 CFA exam this past June. I evaluate & recommend investment managers to our clients (pension funds, foundations & endowments, etc). Having spent zero time at a bank I have essentially no modeling experience. I understand the concepts having walked through countless models with investment managers, but I've never built one myself. Will this hold me back, or is it no big deal?
