I either use four throwing lances or three spears and one lance, mostly four lances though. Note however I'd not be using this if I wasn't accustomed to the throwing lance arch of flight and therefore suck at aiming with everything else. I never had issues with glancing back when I had a much more melee oriented build with 7ps, with my current 3ps and before that 2ps I do however occasionally glance on the higher tier armor as I mentioned, only way to avoid that for me is hitting with the sweetspots and aiming for the head, but really, the stab is what you should be using at least 50% of the time as a spearman (polearm stab also functions very well combined with a few jumps).
Indeed, yeah I'm pretty horrid with lances at the moment; still not used to their arc. I stab quite a lot with non-stab oriented weapons so my stab:swing ratio shouldn't be too bad but still, some time ago when I was using wooden sticks (14b) and had 9 powerstrike, I would glance almost every time on heavily armored foes (from memory, that probably isn't true hehe).
Hopefully if/when I get loomed throwing lances, they won't worry me as much.
