The k4 is more stable than the g14, even if the g14 does turn tighter etc, I find the instability negates those advantages. The other thing that bothers me about the g14 is the two big balls (cowls) sitting in your face. I'll never get used to that.
The Kanonenvogel had 6 rounds per pod, this is not even close to being open for debate.
For the 20mm fans: I've found that the G2 with small ammo loadout and gondolas to be very capable against fighters, leaving the extra 50 rounds off the nose lessens the Ill effects on turnrate and radius, with all those shells flying one can make some pretty wild shots
I dump the BB's as well, but the extra 50 20mms do add around 60 or so pounds IIRC from E6B testing, plus when U get down to ten rds u know its time to rtb as the gonds are empty
its like saying that taking a feather off an elephant will make a difference...
With elephants...a feather might not, but at the end of the night, another beer certainly does!
