Well I really don't like AEGs. One of the reasons I play airsoft is for the realism of fighting, and I like the sound and kick of a GBBR. Unfortunately, I'm only 14, so UKARA really isn't a valid option. Like I said, I have a lot of money set aside so I can play airsoft, and I'm happy to spend another £100 on mags. I really don't want to buy an AEG, I just don't like them. Perhaps in the future I'll buy a G&P M4, but for now I'm sticking with GBBRs, and I adore the G5. I can use a slightly weaker gas, that should be okay. The 350 FPS is coming from .20 and green gas, and I need to get down to 330 with .20s, but they don't specify what gas type I need to use.
