Lowering tension too much leads to less control. I think it best way to approach it is to get the tension to its minimum while still having enough precision, and then if you need more power add some lead to the hoop. Note that if you have to add more than 5-10g of lead to the hoop you probably would be better off with another racquet that has more inherent power, likewise if you have to go down to 40lbs to get enough power.
