I love both these patterns, and both are super effective in resulting different ways-- the muted blending nature of Flecktarn works well especially against the brush and foliage, and the diffusing contrast of CCE (much like US Woodland or DPM) just works, especially in a proper environment like yours and mine with lots of trees and leaf litter, great woodland pattern.
No question, when a camo pattern doesn't break the body shape its efficiency is reduced to the environments of similar colors as long as the light doesn't create to much contrast.
Flecktarn goes better in darker tropical jungles or forests with low light exposure during spring or summer whereas the beige CCE seem to work better during fall or in dry forests during summer.
