Make Better Putts
10 putts a day using a Str8 Putt training aid will give you a complete understanding of your swing and tendencies. With this understanding you will learn where your swing goes wrong and how to fix it. Once you understand the problem, then you can set about fixing it.
Why practice straight back and through? Because you won't be perfect on the course or under pressure. By practicing perfect you are more likely to preform better when the pressure is on. It's the same reason pro's use every device that makes sense to them to help with their swing during practice. If you can repeat perfect during a practice session, then your odds go way up when it matters most.
Str8 Putt helps you practice perfect so that you can preform your best under pressure.
