What lines would suit him?
I’ve noticed IJ gets them initiating conversation with me. I’m 33. Dress in smart casual most times. Man of few words.
“IT’S THAT GOOD.”
How many sprays … TO-GO or 30 mil bottle?
IJ is a great product for exactly that. But if you want to add a bit of charismatic vibe to it toss in some Ammo and tone down the amount of IJ you use until you sweet spot test it to avoid od.
I love IJ, I love TUTH. Being 45, fair skinned almost hairless on arms legs etc I produce less none than your average man so I can use a bit more.
Depending upon the type of girl I’m going for I will tweak my mix with some TUTH or IJ just to spice things up.
I only have a togo bottle at this stage. I haven’t exceeded 2 sprays as of yet.
I find IJ works very well in the “man of few words” mode with A314, fairly high dose.
However you are going to accept that you will repel a lot of women and piss-off a surprising number of guys in the process.
But when you find a woman who responds positively - WOW! 
I’ll keep you posted. What else do you know about how the man of few words can succeed in seduction?
