There are two differences between the Daytona and the Redwood.
Daytona scales 15,30,60,90.150,300.
Redwood scales 15,30,45,90,150,300.
The other difference is the meter speed, with the Daytona having a significantly slower one.
I like the 45 scale on the Redwood but I find that the slower meter speed of the Daytona increases the chance to ding the put.
With these higher precision putters dinging is preferable to the offset putting method. (I do use the offset method for putts 7ft and under).
As for the Spider putter............. the low precision on this club makes it very unpredictable. Just look in the bag of the better players (not me) and count the number of Spider putters in play..........
To sum up...... if you can wait for level 55, the daytona would be the way to go. If you want to get something sooner, the Redwood is a very good putter.
Happy hitting
