I found the 3x C3G beams were just too hot, and I didn't get enough damage out of a full WEP capacitor load, even using the A7 Power Distributor.

Fixed isn't attractive... increase in damage potential is seriously outweighed by loss of on-target time. (~10+% extra damage but can you keep it on target for 90% of the time a gimballed laser wil be firing? Hell no.)
10% no, the fixed is 25% more damage.
You get the more potential damage out of a weapons capacitor with the fixed but you do require more subtle tactics than "make sure the target is somewhere in front of you" to get the full potential out of them. You can hit a Sidey with 2 of your 3 beams at less than 500m thats more firepower than a sidey can handle, for anything bigger than a Viper you'll be hitting with all 3 if you exercise a little firing discipline and train a little to get used to fixed weapons.
As to heat, pop a HS if you have the need to kill a target fast, otherwise work with the rythm of the guns and heat is managable even on a C powerplant, the B plant is only 16m and provides very good cooling with a little discipline.
As to on target time, the Python spends a lot of time off target anyways (if the opponent is half--way decent), your gimballed cannon can help here while your guns will recharge at such moments for more maximum beamage. You can melt through a Python or FDLs ahields in 1 pass with the HSs against NPCs or tardy humans you can down shields in anything smaller before a pilot can pop shield cells, you'll never get that direpower out of gimballed beams.
To each his own I guess, my setup for max firepower has drawbacks such as a well piloted Viper is a PITA (but he can't boom'n'zoom you as your fixed beams can really reach out and touch at 2Km, gimbals struggle around 850m-1km), an Eagle a real nuisance unless you're in reverse, but againsts Cobras and bigger the 3 fixed beams are rampage machines.
