Royal Flush: Garhauer is good choice. If you decide to purchase from them ask for Guido or Mark. Tell them Don Guillette told you to call. Make sure you get the spring upgrade. The standard springs are OK but the upgrades are better.
The only thing with Garhauer is sometimes the installation instruction are a little sparse. If you decide to make the purchase get back to me and I'll explain how I installed the Garhauer vang. One important point is that you want the boom to be about 10 degrees ABOVE horizontal when it is resting on the vang. One person could install the vang, which I did, but a extra person is very helpful.
