You're in a good spot - looks great buzzed down close like you've got it and will most likely look just as good completely sly.
If I were you my curiosity would get the better of me and I would go all the way. If you go for it make the commitment to keep it up for awhile - the 30 is great but if you really don't like it and give up sooner the sly police will not come after you with a bottle of nair. It can take a couple of days/week to get used to.
Just do what feels right for you. My guess is you'll love the sly. And regardless, at the time MPB takes over, you'll already have taken the initial plunge and won't have the issues to contend with again.
