It is complicating to have too many "looks" in the bag. I am currently using Adams 5 & 6 hybrids, a KZG 7 wood, and Wilson 5 wood. While I'd like to have one look there instead of two, I like the performance of the two pairs of clubs. Last time out I had four shots in the low 150's and stuck the 6 hybrid tight each time. And I greened two 7 woods besides. Drop and stop. As well as the 6 hybrid is working, I wish the same model was available in a 7, but it's not. And I'm not going to add yet another look to the bag with some other hybrid.
I also carry a 5 and 6 iron, lol, and still only 14 clubs. I have a 27d KZG 9 wood in reserve, and while it's a good club, it's not as accurate as the 5 hybrid.
There are KZG CH-II 9 woods on ebay for cheap. They will be 27 degrees as far as I know. My CH-III is 27, anyway, so the older one will not be stronger, I wouldn't think. The CH-III 7 wood is 23, so most likely the CH-II is too. I mention this because it's getting hard to find woods much higher than the low 20s. There were lofts into the 30s in the CH-III model, like 11 and 13 woods I think, but I've never seen them show up on ebay.
