shbg and nolva/clomid question

Does anybody know wich steroids have the strongest SHBG lowering effect? I have read d-bol proviron and dht have that effect, any others? and wich would be strongest?
Also has anyone ever compared nolvadex and clomid post cycle, for a two on four off cycle would it really matter if one where to take nolva instead of clomid? Has anyone ever taken Both, each a half dose, this was suggested elsewhere on the net.
Last question: if one where to use only non-aromatizing steroids, is there still need for anti-e’s post cycle to speed recovery?
This is a lot of questions but i hope you guys can shed some light on this.

Just found out formestane has also shbg lowering effects, but wich dug is the most potent?
