Personally I like the A-230, mainly because it was developed by the help of Heidleberg. With the modern rubber used in Maxxis I think it is a better choice. Most preps pull the natural oils out of the tire as well as age, heat cycles and such. Most of your blanket washes help to preserve the rubber by conditioning and adding back some of the natural oils, or at the very least maintaining the resiliency of the rubber.
If you have a easy choice for the mentioned, I would use the V-120.
