as paradox as it might sound, lets say the mig 29 is an f-16 and the su-27 is an f/a-18. The F-16 is gonna beat the F-18 in fast, horizontal fights. The F-18 guy will always try to get the F-16 into its game, which is the low speed area. The Su-27 is remarkably maneuverable at slow speeds, the mig isnt (imho). So...Keep the Mig fast...But..come to think of it...the SU is good at higher speeds too..dont you think?! So..i guess the SU is just more maneuverable than the mig at lower speeds.
