Well normally Technician is for sweepers, but with Poison Heal you have more choices. You can choose to sweep, (with Bulk Up), stall, (with Toxic and/or Spore), or a combo of both. Now, I'm not saying Technician is horrible, because you can totally sweep with Technician and get a 6-0 win if you play it right. But if you ask me, I would normally choose to go with Poison Heal.

~ Bulk Up
~ Spore
~ Seed Bomb
~ Drain Punch
This is a set from Smogon, and it works really well. You use Spore to but your opponent to sleep, try to get some Bulk Ups in, use Drain Punch and Toxic Heal to heal, and there you go. A great sweeper.
