Well like the title says this has to do with getting it close and smooth on the back and sides. I can manage to get the top so smooth it shines and it feels great to boot. But it seems no matter what I try I can't do the same for those though spots (Back and sides) I've tried going with and against the grain, trying a new blade just for those areas, doing multiple passes and i still end up with that unappealing feel of sandpaper. So what do you guys do, is there some secret technique i've yet to master or something? 

I've never had an issue with the sides.  I do have a patch in the back---just south of the crown---that is a little difficult.  I'm BBC, so I just figure that area is just thicker and probably has a swirl.  I use a DE and get the best results. 

For one, you want to ensure there's nothing lacking in your prep.

When you've mastered that (you may already have), I recommend you have a look at mantic59's advanced techniques.  He uses them when describing face shaving, but they are effective for head shaving as well.  I particularly like the "j-hook."

I don't have a completely smooth head (for a myriad of reasons) so there are trouble spots that just don't seem to get completely smooth.

Same here. I cannot get a 100% smooth shave all over on my head no matter what i try!

Thanks for the advice guys. I guess ill just get a better razor (Been using my old trusty Gillette I use for regular shaving) and opt for one with more blades and work on my technique. Till then I guess ill just need some practice (or get a devoted girlfriend to help lol) But agian thanks for the advice, you sly guys are always a great help. 

Honestly, my electric remmington gets the leftover stubble on the back of my head and that stays smooth for a little while.
