A good piece of advice for someone starting out or even someone with a few years under their belt is to try to play a round normally. Then after that round try playing with just a putter. Sometimes you'll be amazed at how good of a score you can get just by using a putter.
If you chose to use a Disc Golf putter when approaching the basket, keep in mind that most putters do not hyzer out as much as a normal disc.
They tend to fly straighter and less distance.
Sometimes you'll find generic discs out there. I find these discs are great for Disc Golf approaching since they tend to not fly as well and won't over shoot the basket.
