jeez what a decision!!!!

After careful consideration into Looks, durability, responsiveness, weight, and componentry. This is my conclusion.

If you are looking at durabilty as a priority factor and weight and responsiveness comprimised, then I will have to say go for the Specialized. On the other hand if you want light and responsiveness then I would go for the Kona Stab Deluxe. The only week points I can see on the Kona are the top cast pivot arms and the rear disc break support arm. I cannot really tell what the strength is properly for the castings on the picture so it will be best to take a look yourself.

And then Finally as everyone always say, try and take them for a test ride, at the end of the day, if the is good backup service then I would go for performance.
