LotFP Magic System

Hi there. 

I'm currently reading LotFP Rules and Magic Book and I'm having a blast with the view of Magic, Magic Users and the twist to some of the spells, particularly "Summon". I'm seriously considering incorporating it into my S&W campaign. 

Has anyone had experience with it? 

The sheer act of reading it (another cautivating example are the "Light" spells) is a pleasure by itself.
