Although this questions is probably the single most threaded topic on
this NG,
I'm going to start a post on it again..
I'm looking for some feedback from others that sail large sails.

Currently I have at quiver that jumps from 10.5 to a 7.5 to a 6.5 and
then 5.5.
the 7.5 is a np v8 and the rest are retro's I'm looking to replace the
7.5 as its seen its days.
I have 2 boards an older *board formula 155 and a 102 litre jp
the 2 larger sails will stay on the formula, and the smaller on the jp,
no problems there.

I'm trying to decide between an 8.0 or an 8.5 for the replacement to
the 7.5

I can ride the 10.5 into a 17-18 mph wind, but, past that, its really
not much fun, I find myself heading upwind just to stay alive all the
time. but, some times the jump down is just too large, and I find
myself slogging on the 7.5 if I switch at the magical 15-6 mph.
So, I'm curious about the range of a 8.5 vs an 8. if anything I'd
rather have more overlap in the 8.X - 6.5 jump than the 10.5 - 8.X
jump. IE if friends are over and it is blowing 15 I can set up 2 rigs
that will plane. So I guess I am leaning towards an 8.0
anyone out there that would try to convince me otherwise and would
suggest going with the 8.5?

The thing that makes me hesitant is I want to make sure that when I do
switch from the 10.5 down that I will be planing on the 8.0.

Thanks for your input.

8.0 and 8.5 are very close. I doubt it would make a whole lot of
difference, especially when sizing down from the 10.5 (the style of
sail will have more of an impact than the size). However 8.5 to 6.5
may be a bit of a jump (almost 25%), so all else being equal, I would
err towards the 8.0.

I made a change like this several years ago.

Old quiver: 5.5, 6.5, 7.5

I replaced the 7.5 with an 8.8 race sail (Aerotech VMG), and learned to
downhaul it well. I had no problem at all with "too much wind for the
8.8 but not enough for the 6.5."

Just make sure you buy the formula outhaul from Bruce. It will help you
change the power on the fly. It is exactly like having a transmission.
Low to get planning then pull it out into drive when the gusts hit.

I agree, it will be difficult to tell much of a difference between the
8.0 and 8.5.

I guess I vote for the 8.0, but I don't think you can lose. I agree
also, be sure to get the A.O.

Dave:

Get the 8.0. That is what I have between my 10.5 and 6.5 - on an old
Formula 175 - and it works. When the 10.5 is OP'd I ban jump down to the
8.0 and be easily planing. When OP'd with 8.0 and F175 I put the 8.0 on my
ProTech ATC 270 until OP'd there.

Dave,
here's my $.02 on the issue...

A 102 liter board is really pretty much maxed out with a 7.5. Anything
larger just doesn't buy you more low-end. And if you're not getting a
lot of overlap between your F175 with the 10.5 and your 102 liter JP
with a 7.5, I'd say the solution is not to get an 8-ish sail to put on
the F175, but to downhaul the 10.5 some more and use a smaller, more
slippery fin. Not sure what fin you're using now, but I'd guess that
something like a 66cm R13 would do the trick; maybe even a 64.

By the time I get well overpowered on my 10.8 NXfw with my Roberts
Formula board, I can usually get very nicely powered on my 7.2 NX4 with
my 24" Roberts slalom (about 100 liters). My 9.9's top end is somewhere
up there to where I'd be lit on the 7.2 in slalom mode.

I often see people opting for a whole separate mast/sail/boom combo for
their formula gear when a single fin could get them as much additional
range. Formula gear tends to get unruly because of tailwalking (caused
by too much fin, or a fin that's too soft and lifty for the amount of
power you're working with) and sticking the nose downwind (which is
also exacerbated by a big fin 'tripping' the board off the breeze). See
if you can borrow a smaller, lower-drag fin from someone and try this -
you'll find there's a whole new gear in your formula setup.

I go from 8.0m to 6.5m with no problem. The transition works pefect
for me with no gap in-between. When overpowered on my 8.0m, the 6.5m
feels just right.
