I got so much advice on stabilzing a 6' Rok that I thought I'd try 
again.  That one is flying pretty well now but is heavy and wants a lot 
of wind.

What should I consider as far as lowering the weight.  I could use 
dacron or nylon pockets for the pockets, I suppose.  I could use lighter 
spars on this one.  Are there any guidelines about spar selection for a 
Rok to be flown in low wind only?

>From what I've read, it seem like a 6 point bridle might also work 
better in low wind.  Are there any comments on the bridle?

Thanks in advance.

A six point bridle is meant to distribute the load better in high wind. I 
can't really think of any advantage in low wind!

The nicest bridle on a rok is the 4 leg bridle with a centre piece 
between the top and bottom legs. This can be modified to become a 6 point 
bridle but is then not quite as easy to adjust. A full description of 
this is archived somewhere - Is also on my rok design which you can find 
off http://hickory.egs.uct.ac.za/~rodger/

Cheerio

I'm not a Rok flier.  (I must really get round to building one)

However, I would want to use more bridle in a light wind, to allow me
to get away with using lighter sticks.

Although the extra support could support a lighter frame!

I agree.  All my roks use this kind of bridle.  However, I understand that
the traditional roks use 7+ point bridles to support their flexible bamboo
frames.  Using a multi-point bridle, I see no hard reason why an 8' rok couldn't
be framed entirely in microcarbon (this would of course require a *lot* of bridling).
Now, if someone bumped you in battle, well, then, that's another story but I think
the light wind characteristics would be interesting.
