I complained about putting so much that we had a contest of what putter I should stick with for a year. I gave several options of what I was willing to try out and the XT Whale won/lost. So, I am for better or worse stuck with XT and Champ Glow Whales until June of next year.
Inside of 20 feet, I have no problems with them. I have traditionally had issues with either putting low and hitting the front cage, or putting at the correct height but missing to the right. Not that my putting woes have gone away with the Whales, but within 20, definitely within 15, unless I completely sally the putt, I have not had many misses. However, for reasons I cannot explain, all bets are off at 22.5 feet. I am not sure about why that exact distance, but I could miss anywhere with no consistency.
I have a Gold Line Pure that I start using from that distance, and more recently I have been attempting long range putts with my ESP Comet. Just for the fun of it, after a couple of drives with my ESP Zone, I even putted with that. Basically, I have so little confidence with the Whale as a putter that once this experiment is over next June, I am likely going to be trying something else. Six years ago I was having mild success with the Voodoo, and I have been itching to give it a try again. I only went away from it because for a short time I was obsessed with making a Trilogy bag work.
For a driving putter, the Whale is decent, but I easily rate the Wizard and Ion above it. Unless there is some serious wind (but not enough for the Zone) or serious elevation drop, I always reach for my Pure first.
