When I first got to L98 I rented the Sabertooth and HATED it. I did not buy it when presented with the discount, and instead kept using my L55 Daytona (which, as an aside, I still think is the best "bang for the buck" in the pro shop).
Each time I'd play with a clubmate who had the L98 Sabertooth I'd ask them about it, and they all said "it took awhile to get used to, but now I love it". So when we got a free rental weekend awhile back, I went ahead and rented it for two days and played with it a lot. After a couple of days I could see it's merits, so I went ahead and bought if for the discount after the free rental weekend ended. I've never looked back. I think the longer you use it, the more you'll like it, especially on longer putts at faster green speeds (12+).
