This 2018 Marucci F5 BBCOR Baseball Bat: MCBF5 is a one-piece alloy bat which is the most conductive for vibrations on contact. Thicker grip tape can help reduce the vibrations felt on the hands. However, if you are truly wanting to avoid negative feedback we would recommend looking at either a hybrid (alloy barrel/composite handle) or a fully composite bat.
The CAT 7 BBCOR bat does receive a little more research and development in its design. Both this 2018 Marucci F5 BBCOR Baseball Bat (MCBF5) and the CAT 7 feature AZ4X alloy. However, the CAT 7 features an optimized barrel design that allows for a bigger sweet spot on the bat. As well, it also features an anti-vibration knob that the F5 does not feature.
The handle of the 2018 Marucci F5 BBCOR Baseball Bat: MCBF5 will be the same as Marucci One and would be a good bat for a college freshman.
