The runner thing
I hear you. Generally speaking the rig is amply supported. The fore and aft lowers DO cover the issue below the lower spreader, but not above.
The thing is that in a heavy seaway, the mast will move more in all directions, which can fatigue some parts if not stabilized. With a full main and headsail, you probably do not need them unless it is extreme, but when you are reefed, and have a short hoist headail, the load/support on the mast changes, and it is here where you have more tangible support from runners (located midway betwen the upper and lower spreaders). In a worst case scenario(mast failure) and you are making a jury rig, this gear for the runners could be perfect for improvised rigged shrouds, etc.
The other benefit, of course, is considerably more control over sail shape. Let's say you are headsail reaching in light to medium conditions with large ocean swells. The seas will be forcing the mast to move a lot, and the headstay especially will be jumping around more than you would like. The solution is to add some backstay of course. But, it could be that in doing so, you overflatten the mainsail (from mast bend) for the moderate conditions. This translates to reduced performance ( could be a knot of speed in these conditions), and that "underpowered" feeling (ever drive a FORD Pinto?) If you crank on a bit of runner, you can "unbend" the mast, power up the main without losing headstay tension..
IIRC, the tangs in the mast are provided. For me, I would view them as cheap insurance, responsible seamanship, and added performance. Will it make all the difference? Not likely, but there are some situations where it might. This one is kind of a personal choice-I don't think are needed for a cruiser doing coastal cruising, but if you plan on heavy trade wind sailing or ocean passages, I'll take 'em!!
Make any sense?
Cheers!
