I'd have to say that the Vibes and the Avalanches are the best overall values in the low end price segment of the bowling ball market place.
That is based on the wide variety of USEFUL, full range ball reactions within the same family, for the same price.
I'd suggest that the best single ball, capable of the most varied ball reactions with changes in drilling and surface, is a tie between the Blue Vibe and the Avalanche Lime/Green.
Yes, the Blue Vibe is still available!! It is very reminiscent of the Messenger Ti in its utility.
