It's a good deal better than the old SBO. Spreads the weight
better, can hold alot more, and is considerably more comfortable.
For commanders, who have to carry signal sets, maps, compasses,
writing materials, and pen flares in addition to the normal load of
ammo and stuff, the new webbing is a god-send.
For M203 gunners, there are now pouches for their 40mm grenades. Of
course, most of the time there aren't enough dummy m203 rounds to
force every gunner to carry 8. In fact, there usually aren't enough
dummy rounds for every m203 gunner to carry ANY. 
So in peace-time, those pouches remain
unused, and the m203 gunners just dont appreciate them.
For SAW and LAW/Matador gunners, they all use the normal magazine
pouches. Our SAW gunners still have to lug 18 magazines for ATEC
and as an OPS load.
Naturally, there isn't enough space on the webbing to fit all 18
magazines, so that's still 1 problem there. But personally, I dont
think its a fault of the webbing but of the weapon issued. No
problems for LAW gunners; they appreciate the wider straps of the
webbing, as it helps prevent the LAW strap from sawing into their
shoulder all the time.
The best feature about the new webbing is the fact that it's
modular. The MOLLE/PALS webbing allows you to tailor your webbing
to suit your load and appointment. By right you're also supposed to
tailor the webbing to suit your mission, but most units have a
standardised load for each appointment, and the men cant stray
(very much) from it, no matter the mission.
Yes, the webbing it hot(ter). And yes, you will have difficulty
leopard-crawling and worm-crawling in it. But with regards to heat,
I first wore the LBV with a bullet-proof vest and went straight for
a mission without much prior acclimatisation or training, and found
it tough but manageable. Some training will allow the soldier to
operate in the LBV very efficiently. Train for it. If your sole
grouse is that the LBV is hot... then you need to toughen up.
