If you send it in to Demarini they'll either send you a new Cf3 or a Cf4 depending on what they have in stock at their warehouse.
It is a matter of choice.
The price of a Demarini bat varies by the type and barrel size. The average Demarini bat probalbly costs around $200-250.
In my oppinion it would be the COMbat or a CF3 Black.
The Demarini CF3. The Demarini CF3. Umm, no. Easton Stealth is the best selling. It has come in many models over the years. Check out www.baseballbatreviews.com/baseball-bat-reviews/easton-bat-reviews for some quality information on baseball bat reviews.
the exogrid is better for contact but the cf3 is better for power
Well, the Easton Stealth is a fairly good bat; which as the CF3 is amazing. I have one and I hit bombs. The Stealth takes longer to break in, while the CF3 does not. But when the Stealth is broken in it's amazing too, but i would go with the CF3.
cf4
Yes you can! Especially since it's aluminum... I recommend a composite bat though. Composite bats have way more pop than aluminum bats. I would recommend the cf3 or cf4 for a new bat. Or try the stealth!
the cf4
either is a good bat but i had the sv12 and it cracked
The carbon atom in CF4 has a hybridization of sp3.
the cf4 is the better bat it has great pop
