My question is: how does Overcoming Gravity by Steven Low compare to BtGB (F1, H1, etc)? The reason I ask is because I brought Overcoming Gravity awhile ago, and liked it, but I have not seen a ton of success stories from people using it (unlike BtGB). I will not be able to afford F1 or H1 until this school semester is over, so I was wondering if following OG would be fine... and for anyone who has both F1 and OG, how similar is F1 to OG? Because if they are very similar, I will probably not buy F1, just H1.
