Those Neu Energy packs are Enerland packs I assume? If so, the G3's are more than worth it, they should last alot longer, provide you with intense punch, and are just a better/newer cell chemistry plain and simple.
Ask Mike, he will say the same.
EDIT: Plus you can charge them at 5C, and I do charge them at 5C everytime I use them! 20 amps for the 2x 3s/4200mah VX packs. I must have done ~70 cycles on them by now, I use them multiple times per day and charge them right after each use, and out I go again... they never get over a few degrees over ambient (10 degrees tops) the whole time.
