You can't put a draw or a fade on a putt, right? So if you can't hit a straight putt, no matter what distance, you'll only get worse when you try to trust a putt straight down a line that is not straight into the hole.
Not trying to be a smart arse....lots of info is lost when only reading. With that said....were you kidding when you said 'you can't put a draw or a fade on a putt, right?'.
Not in the sense of watching it curve in the air, but if you had to guess what happens to a putt when you hit it with the blade 3* open? For starters, it ain't goona go left.....it goes right just like a slice with a 7 iron would at 3* open.
Oddly enough, I'm left eye dominant so L to R breakers are my fav even though I'm a right hander. I don't see the line as well for R to L breakers and don't like them as much. Slice putts are my fav and when I'm really striking it well I try and put all my approach shots left of the stick. Talk about weird.....most righties hate slice putts. I'm an avid duck hunter and shoot lefty as well....just an oddity. I have a right handed pal who putts with an old Bullseye and hit nothing but slice putts....switches to left handed when he has to so all putts are slice.
