It does matter. I know it is simply anecdotal evidence, but we went "pure" last season and didn't use Robos. We also had a terrible season. Each club around us had at least one spinner running. Some had up to four running.
This year, we took the low road and put out either one or two spinners each time, and had a good season. Again, this is anecdotal and not a sophisticated study of all the variables, but I can assure you that our shooting skill was no better and our calling is probably as suspect as ever.
Until they outlaw the spinner, we believe we have no choice when we are surrounded others deploying the same tactic.
