Just on a slightly different point but still about practice.
Would it not be possible for WGT to sell what i would call a ghost ball of various types only useable in practice rounds equivalent to those we can buy in the club shop.
If they sold a ball for say 100 credits that like the free ball never wore out but only useable in practice mode people might experiment with different balls more and it may even increase WGT's revenue.
I for one object to having to map and get used to expensive balls ,2 sots for mulligans etc in practice mode.
Hope i explained my idea ok.
