I like the JRC 1000 or 1500 with one exception. If you try to run the feed
line inside the mast it requires drilling a larger than normal hole and
thereby degrades mast integrity. This means the best way to mount is either
running the line down a lower shroud or using the aft pole mount system.
The higher the better is the ruile but it depends where you are going with
the boat. For coastal cruising, harbor entrance work etc. the pole mount
will work fine. For offshore you definitely want all the altitude you can
get. For the actual mount the swinging kind is best but spendy.
