The OP currently uses the wgt GS-13 ball...99 cents ($1.08 because of color option). They are rated 0 for distance and 1 for spin. His clubs are decent though.
Not quite sure it's even worth considering a Nike until the specs can be mastered. Many ball options are currently available, which are far better than what he is using... and much cheaper to buy than the Nikes.
My personal opinion is the Cally 33 is still the best value ball...but as was previously mentioned, dedicated practice is required; regardless of the clubs or balls you use.
