vega reds vs vega yeloows

Yes they are fast soft in high twenties all the way up to 70. Reds i am refering to. I really like the red vega would choose them over a firestone or maxxis any day. Ive only run yellows in the twenties fo qualifying and practice deals.
They are good as long as they are fresh. I feel like they aren't as good the older they get. But in a situation when they are on a high bite track I think that they are a lot faster than the yellows
