Positives
- more hitting power
Negatives
- more hitting power (can be too much at times, depending on your strength and rev rate)
- lower ball speed (depends on how long it takes to get used to the heavier weight)
- rev rate may change (just the fact that it changes means a different ball reaction)
- if you're not strong enough, you can get tired quicker or lose that firm or cupped wrist in the later stages of league or long tournaments.
Neutral
- RGs and RG differentials and MB strengths are different in 15s from 16s, sometimes more/higher, sometimes lower/fewer. This means a different drilling is required to get the same ball reaction, depending on rev rate and ball speed
