I'm currently using a Barrage + Bears variation and loving it. MP6 is doable solo although it's obviously not as efficient as on lower MPs.
I've tried a pure Bears build and a Bears + Spiders + VQ build, and while both are fun to play I'm really fawned on the variation I'm playing now. Bears are very powerful but can be tricky to use against Wallers or enemies that you need to kite a lot. With Bears + RoE + Barrage you have strong burst against groups or single target with your back to a wall, and a strong sustained attack that can be used at long range and ignores most walls.
The other change I made was substituting Horrify for Zombie Dogs w/ Life Link for a constant 10% DR rather than 800 armor. Truthfully I'm not sure off the top of my head which would be better in terms of sheer damage reduction but I've used that on other builds with good results.
