Help Me Let Dragonite Sweep

So I built this team around Dragonite, and it's more or less just a bunch of Pokemon slapped together on a team one after another. I put each Pokemon on the team based on role instead of coverage and well.. It's worked out all right but I want to see improvement.

The team:


Modest @ Air Balloon
252 SpA / 4 SpD / 252 Spe
Flamethrower
Earth Power
Hidden Power Ice
Stealth Rocks

I lead with Heatran and set up stealth rocks on the first turn. Then I usually jsut switch it out and back in depending on when I need it. I opted for Flamethrower over Fire Blast because the latter has done me more harm than good. Earth Power and HP Ice for decent coverage.


Adamant @ Leftovers
4 HP / 252 Atk / 252 Spe
Swords Dance
Bullet Punch
Brick Break
Bug Bite

The revenge killer and potent sweeper after a SD. I opted Bug Bite over U-Turn because the latter makes it relatively pointless to use Swords Dance. Bullet Punch for priority and Brick Break for coverage.


Timid @ Leftovers
4 HP / 252 SpA / 252 Spe
Rapid Spin
Surf
Thunderbolt
Recover

Starmie is a great partner for Dragonite. I usually put Starmie in the turn before I switch to Dragonite. The reason for this is that entry hazards are not friendly to the big dragon. Starmie has the ability to get rid of them. Not only that, but it resists Dragonite's greatest weakness in ice. That and the fact that if and when the opponent tries to target Starmie's weaknesses, Dragonite can come in and completely wall the hit either by resistance or through multiscale.


Adamant @ Lum Berry
20 HP / 252 Atk / 20 Def / 216 Spe
Dragon Dance
Dragon Claw
Roost
Fire Punch

The reason I'm trying to create this team. It's a pure monster after a DD or two and with SR support, it can KO a majority of teams by itself. I'm using a custom set to provide more bulk while still keeping the firepower. I'm not too worried about outspeeding scarfed pokemon and with it's bulk and multiscale, it can usually tank a hit anyways. I might replace Roost with Earthquake and switch Lum Berry with Leftovers. Problem is that people love trying to status Dragonite and with Lum Berry, I can get away with one. Thoughts?


Modest @ Life Orb
4 HP / 252 SpA / 252 Spe
Nasty Plot
Aura Sphere
Dark Pulse
Vacuum Wave

I needed a special sweeper and the 5th generation has been very kind to Lucario with NP. Aura Sphere get's STAB, Dark Pulse for coverage, Vacuum Wave for priority/revenge.


Jolly @ Life Orb
52 HP / 252 Atk / 204 Spe
Agility
Meteor Mash
Earthquake
Ice Punch

For this final spot, I pretty much just threw someone in that I thought would be a nice partner for Dragonite and Metagross fit the bill as it could take attacks Dragonite was weak towards. I usually just try to scare off opposing Pokemon and Agility up and sweep from there with Metagross, not much else to add. Meteor Mash for mandatory STAB and potential +1 in attack, Earthquake for coverage, Ice Punch for dragons.



So there you have it. It's worked decently but I think that's more along the lines of the opponents I've been fighting being terrible. I've been trying to find someone to absorb electric attacks but haven't found one I like yet. And as you will probably say, I know this team has terrible coverage, which is why I've come to you guys. Having 4 steel types doesn't help either.. Help?

Hmm.. I'll try that out, thanks. I'm also thinking of putting Landorus in to absorb Electric attacks? The thing is that 4x weakness to ice..
