Goin from 4 to 8 tabling

[Steve09797]

A couple weeks ago i started eight tabling at 2/4 on party poker and have hit one hell of a dry spell. i was averaging about 5 bb/100 hands four tabling, which i knew was bound to drop down a little but i did not expect to get hit the way i did. i lost about 300 BB in the course of three weeks, but dont really see much difference in my VPIP and agression. im considering going back to four tables after a couple more shots at eight tabling and was just wondering if anyone else hit this problem when they changed. just yesterday i downloaded playerview, so hopefully that will help me. does anyone have any other recomendations. i appreciate the help.
