Please help in choosing a 9.5 sail - cam or no cam?

Guys,

I got 2007 Daytona 10.0 the other day. I sailed it a couple of times
(low wind + few stronger gusts).
What can I say...what a great sail. Great piece of technology, feels
(and looks;-)) like a Formula racing car but was easy to handle.
Rigging is a joke, it rigs better than my Gaastra Matrix (no cam).
Insert the mast (the pocket is wider, so it gets in easier) above the
cams, dowhaul 70%, outhaul to the max (so the cams get in easier),
open the cam pockets, push the battens down so the 3 cams get on the
mast (they have rollers and get in very easily), finish/correct
downhaul/outhaul and voila!
It pulls very strongly, but gently, sort of like you had your board
pulled by someone with a rope, funny, soft feeling ;-). It doesn't get
crazy with the gusts or wind direction changes - it just gently
informs you that you need to adjust to the new conditions. I guess
this is the effect of cams.
It rotates very firmly, too.
It is heavier and more difficult to carry or get off the water, but
once it's up it feels light.
I can't wait to try it when the wind is stronger.
I use the carbon extender with my 490 and on the sails it says it's
the "best" combination, whereas 520 is only "o.k."...why would North
put it this way, not the other (520 "best"), if it wasn't the case?
The only thing I'm not sure is how to use "visual downhaul marks" that
are on the sail (for outhaul it's obvious) - any thoughts?

So I guess I'm pretty much done with my sails for that board (FT 148).
I'll keep 7.5 for these really strong days and try to use 10.0 in all
other conditions.

Cool, I'm glad you're happy with it! I sail my 10.5 into the low 20's,
so bet you will be thrilled with the range. Big sails have come a
long, long way.

Marek:  Your question about why 490 plus extender versus 520 without
is because of the inherent stiffness of long masts.  Your probably
familiar with the IMCS system that roughly describes the stiffness of
the mast.  I don't know of any 520s that are as soft as a 490.  More
importantly, the location of maximum bend with the 490 sitting on top
of a fixed extender is higher than the 520 by itself assuming the
masts have identical bend curves.  If the Daytona was designed around
the Fiberspar Reflex 7000, which it very well could have been, I
suspect that Jeff Henderson or the other fellow who designs the flat
water sails prefered a more flexy top than the large Fiberspars have.
This may be consistent with the amount of overall luff curve in the
sail, but I don't know how much luff curve it has, so that's pure
speculation.
