Tightrope: The extra spin gives you flexibility and using full bs everywhere is just a waste of that flexibility.
The flexibility of the distances using spin is a very good point Tightrope! We sure could use a "SpinPal" from WGT to more accurately judge the amount of spin applied. It is hard to be consistent and especially so when using different balls.
Something like this would work.
As we move the spin dot we see a numerical readout of the position. 4 decimal places would be sufficient for most players. ;o)
