I know for a fact that the Probuild three piece wing Synergy was overweight (i.e. >11lb) with the three piece wing. The owner has now purchased a Carbon pipe to get just under the weight limit but really this model should be able to be built at around 10lb and the characteristics will suffer even with the increased power of the DZ's.

A few years ago I tried the same thing with a two part wing for my Caprise again via Probuild, and this came out at 10 3/4lb despite all the best efforts to keep the weight down. The wing itself weighed 3lb 2 oz; I replaced this with a one piece wing from ZNline and lost 3/4 lb immediately!

Sure the transport facility of two and three part wings is great but a heavy model will always hold you back and may ultimately not be worth it.
