Lots of thoughts on this one.

First, in the interest of candidness, I use 3/8" VPC with an eye on each
end.  I attach EACH sheet to the clew with a soft shackle.  Why?  If I ever
want to do a sail change on the fly, each sheet must be attached
separately.  OK, I'm probably more on the racing end of the spectrum than
most.

Here's the picture (ignore that it's my blown out cruising sail rather than
my nice Mylar/Kelar racing genoa):

However, cruiser or racer, you will benefit from soft shackles.  My 35-1,
like yours, has double lower shrouds.  Sheets attached with bowline knots
hang up on the forward lowers.  The difference between bowlines and soft
shackles is significant.  Our 155% genoa now glides through the
foretriangle rather than hanging up.

So, a strong vote for sheets with an eye and soft shackles.  Whether you
use one or two soft shackles is your choice.

Also, why do I put an eye in each end of the sheet?  Simple, at some point
in time you may want to swap ends.

Now, what line?  Do you primarily sail with a 155% genoa?  If so, the the
distance from the clew to the winch is not great.  On Touche' it might be 6
feet.  At 2% stretch, that's 1.5 inches.  However, a 155% is the LEAST
loaded sail.  The foretriangle on a 35-1 is about 320 sq. feet.  155% of
that is about 500 sq. feet.  At 10 knots of breeze, that's about 215 pounds
sheet load.

215 pounds of sheet load is only about 5% of 3/8" StaSet's 4400 pound
breaking strength which equates to about 0.7% stretch (
https://www.ropeinc.com/sta-set.htm).  So now 6 feet of sheet will stretch
about 1/2 inch.

If you sail with a 100% jib in 20 knots and 12-14 feet of sheet that's a
whole different scenario and I'd recommend upgrading to a more high tech
line with more strength or to a larger line.  The load goes up to 550
pounds.

Probably too much info but shows you that what seems like a simple decision
is really not.
