In pct I wouldn't worry about having "too" strong of an aromatase inhibitor unless you're worried about libido, inwhich case you can back the dose off, but aifm does work well.
To the poster, you'll want to use a SERM and Ai's are optional in PCT, nolva is popular because it was pushed hard and is effective,clomid is ages old and known to work. I liked nolva until I found about some of the nasty side effects, even the though clomid has some sides I think it is the lesser of the two evils.
