Everything I've seen and read is unless your racing it you probably don't want the kevlar bands. From what I understand they are too tough and don't break in quick and work as well for the street. As far as the clutches I've not heard anything bad about the red's. For the servo's the "A" has the 3rd largest apply area for all the stock units. It's not a bad unit. here is a list of the size's of the stock servos.
SERVO SIZES
Sizes
'A' 2.825" apply 3.785" release
'B' 2.710" apply 3.785" release
‘C’ 3.120” apply 3.785" release
'H' 2.960" apply 3.785" release
'K' 2.375" apply 3.355" release
'N' 2.560" apply 3.785" release
'O' 2.460” apply 3.785” release
'R' 2.820" apply 3.265" release
