I bought the Level 92 Ghost Spider. I tried several times to adapt. Gave up. Sold it back and don't want to use it again. I missed more putts with that putter than with the Beginner's. But the Daytona is my choice. The problem for me was the scale. Hate 25 and 50..... With tournament speeds, you can expect your 15 feet to go up to 20 feet or more with little elevation or none. 30 divided by 3 is 10....So you can judge easily where 10 and 20 are in a 30 feet scale. 5 is half 10, 25 is easily between 20 and 30... so what do you need a 25 scale 10 feet after a 15? For longer putts, say 40 feet I can easily either use the 30 scale if it is downhill or divide 60/2 and have 30 and add a bit more if I need to and get 40, 45,..... But I guess people that adapted to 15, 25, 50 already know what to use in each case. My other point in favor of the Daytona is that using the 30 feet I can still judge some short putts and ding the meter more easily. It's an excellent putter, and at a wonderful price. I regret having bought that Level 92 putter, I love my Daytona...
