Modern Warfare 2 Best Custom Class?

I’m rank 66 (not prestiged yet) and i was wondering what a good custom class was. I currently use:

For Team Deathmatch and Domination:
UMP45 with FMJ
SPAS-12 or Stinger
Claymore & Stun Grenade
Marathon Pro or Scavenger Pro
Stopping Power Pro
Commander Pro

or (what i use most of the time)

SCAR-H with FMJ (Extended Mags sometimes)
SPAS-12 or Stinger
Claymore and Stun Grenade
Scavenger Pro (Bling Pro if im using Extended Mags)
Stopping Power Pro
Commando Pro

for Hardcore Search And Destroy:

UMP45 with Silencer
SPAS-12 or (sometimes)M93 Raffica
Claymore and Stun Grenade
Sleight of Hand Pro or Marathon Pro
Stopping Power Pro
Ninja Pro

I was just wondering if there was any other good suggestions because recently i’ve been noticing that the SCAR-H hasnt been doing too well for me for close range(for medium to far range its BEAST) and the reloading does do my head in at times as i get killed while reloading but it doesnt happen alot. So i was wondering if u people had any suggestions to help me improve my classes or give me opinions on completely other ones. Thanks.

P.S. I’m the kind of player who doesn’t run out like a headless chicken but i gradually work my way through the map checking if there’s anyone behind me or flanking me. occasionally i do run out but i’m definitely not a camper or someone who rushes, i’m sort of the middle who sometimes runs out. hoped that helped.
Thanks again =)
