BrutalSlice:how many increments does the anser have in terms of how many times you see the putter move as you pull it back?
Anser is 6, 6, & 3 on the 15ft. 2.5 movements basically. I could be wrong, but you might try 10, 10, 5 on your spider.
From what I remember of using the Spider you are correct with the increments Niv. 10, 10, 5
