Riot Shield Class?

Anyone know how to effectively use it? I can pile up assists, half the time in the double-digits, and it's a beast on defending/capturing flags on certain domination maps, but otherwise my KDR always suffers when I use it, generally going 6:15, 8:12, 11:16 etc (My best with it is 10:8). I've been experimenting with Perks and such for it, testing things out. Here's what I got:

Primary: Riot Shield w/Faster Melee
Secondary: Machine Pistol (whatever works best- I like the MP9 w/extended mags right now)
Lethal: Throwing Knife
Tactical: Concussion Grenade

Perk 1: Sleight of Hand Pro (Faster reload + Faster swap weapons] OR Blind Eye (immune to air support and sentries)
Perk 2: Blast Shield Pro (Reduced explosive damage + Resistance to flash and stun)
Perk 3: Sitrep Pro (Detect enemy explosives and tactical equipment + Enemies make more noise and friendlies make less noise)

Strike Package- Support: CounterUAV [5], Stealth Bomber [14], Juggernaut Recon [18]
Death Streak- Final Stand [4]

SoH is great because faster swapping weapons when your primary weapon is a defensive one can save your life, and faster reloads are always nice. Always annoying when you get killed by a stupid chopper, so I sometimes use Blind Eye. I prefer SoH pro though.
The second perk you could easily use any of them. Overkill Pro would be nice with an assault rifle to go with that shield. Hardline Pro would be awesome by reducing kills needed AND by counting 2 assists for 1 kill towards killstreaks. Assassin Pro is great for any class. The reason, however, why I've been primarily using Blast Shield Pro is because explosives are, besides getting flanked, the top reason for death with this class.
SitRep Pro is used because nothing else there is of much value. Would love to trade this perk out for one of the ones in Perk 2 category.

Thoughts?

You should try earning an akimbo pistol, works great with the riot shield.

Akimbo pistol or Akimbo Machine Pistol?

The only time it was acceptable to use commando in MW2. I had a bash (literally) with it, hit one guy and then before I could get another shot off he had shot me. COD games have too much latency to use them tbh, might be alright for capping a few flags but it's going to be difficult to get the melee proficiency for it

This is what I would have providing you have all pro perks available

Riot Shield
Weapon of your choice

Scavenger Pro
Overkill Pro
Marksman Pro

Specialist
Sleight of hand
Quickdraw Pro
Steady aim pro

Someone who has those try it out for me please

Yeah you get M60 big ammo, what do you get in the support one?

Yeah, I think Specialist package works better since you don't need so many kills.

Riot Shield
USP Tac Knife
C4

Sleight Of Hand Pro
Hardline
Sitrep

Specialist
Scavenger, Blast Shield, Assassin.

Just switch to USP when they reload and knife them.
When you are able to, throw a C4, back up around a corner, and wait for them to walk around. This'll earn you scavenger so that you can replenish it.
