Inside Down The Line is by far the best putting training aid. I bought the combo package which has the short & long track and putting mat. Used the advice of Angel Cabrera's coach, Charlie Epps (on the DVD which comes with the tracks) of putting 60 putts each day for 60 days... I shot my lowest round this past Sunday, 77 with only 11 putts on the front 9 and TEN One putt greens The Short track is excellent for putts inside 6 ft. I take it to the course fits right in my bag. the longer track is used with the putting mat but can also be used for long range putts on the practice green this aid is WORTH EVERY PENNY !!
