Java 4+1 (OK, but narrow belt/clasp setup and horizontal pod pockets make for a bouncy run)
Java 6+1 (thinner material than their 4+1; a bit ultra-large)
Proline 4+1 (flimsy construction; no stiffeners on pod pockets) Crappy product.

Review:
I like this pack a lot. The super-wide Velcro belly band is very easy to put on for a secure fit.
It holds four 140-round pods, with elastic loops for two more, if needed. This brings the capacity up to a 6+1, without the big fat profile.
The pack will not bounce when running or gradually settle down on your waist.
The vertical pod layout makes for a narrow profile.
The pod pockets have stiffeners at the bottom, which makes for much easier reinsertion of pods after loading.
The only bad thing about this pack for me is it will not accept my Crossfire 92/4500 with the tank's neoprene cover on. Without the cover, the tank slips in securely, but you lose some protection. Redz should consider adding a half-inch to the tank pocket's inner diameter to fit the big tanks without compromise.
A 68 HPA tank with cover would fit fine. As it is, I may have to modify the tank pocket to fit my 92. Too bad.
Conclusion:
Highly recommended. Many players that have seen me with this pack and tried it have bought one for themselves.
