"I have read that going from 10% to 8% is a whole different ball game. Anyone been there?"
actually, from my own personal experience, the 7% mark seems to be a real ass-kicker!!! taking it under 7% was a real bitch for me
although, my alltime best was 4.6%, as it stands now i'm roughly 12-14% i plan on trying to hit sub 7% by may, if you'd like some tips just send me a message. peace
