What do you think of my MW2 loadout?

Right now my main loadout where I get many kills is as follows:

M16A4 w/ grenade launcher

M9 FMJ

Frag

Flash

Slight of hand pro

Stopping power pro

Steady aim pro

Martyrdom

My second one I use sometimes:

RPD foregrip FMJ

.44 MAG frag

flash

Bling pro

Stopping power pro

Steady aim pro

Martydom

Others I have used In the past with many kills are ump, pp2000, grenade launcher, scar, and silenced rpd.

Do you guys recommend any more things to add/replace to my loadouts? I've unlocked like every thing, so suggest anything.
