You've said you're using the HB. A lot of guys use them with great results, others, like me don't get such great results. You might want to try some other weapon, like Fusion. Also, are you scraping the grape right after waking up? Wait at least an hour if possible. Are you using Headslick? Do you put it on after some oil like Shave Secret? Have you used a scrub? I use a loofah sponge pad--Wal-Mart about $2-3 with my shampoo.
Then, like the answer to the age old question, "How do I get to Carnegie Hall?", it's just practice, practice, practice. You'll find what works for you.
