eheh I dont know to stone or lbs, I use kilos 
For the interaction I recomend, IO, makes easier the talking and the pick up it makes people more talkative more open hence the name 
, also I would tell you to read some good pick up books on the matter, I recomend Neil Strauss - The Game
You already have instant shine, so pair it with IS for the combo social, you will like it
for knowing your tuth treashold I recomend you to read: How to find your sweet spot...
other than this ammo will do the trick Really get ammo, for me the best and I think also to atract the younger ladies
