I like the flat top putter/approach discs. In fact, I putt with them too (I use a Rat, but that is because I like the plastic, the Harp and Zone feel the same in my hand). I hope Dave comes back and does a less stable version of this presentation. There are almost no understable versions of the flat top approach discs. The Lat Spike being the only one I know of. It is very understable and I wish it came in a high grade plastic. That said, Infinite has a flat top stable approach disc called the Tomb. It is flat out my favorite approach disc. It is rated 3 4 0 1, and it delivers. It stays straight with a fade at the end, but not a hard one. If you get good snap on it, it will stay pretty straight with almost no fade. If you are not a massive arm, and you want something like a Zone or a Harp, but find they dump too fast for you, this disc might work for you. Note, for me, the I version dumps more like a Zone, and I prefer the S version. It is quite nice and surprisingly comfy in my hand.
