A wheel is a "system" of hub, spokes, rims & nipples.
It's only as strong as the weakest link.
Strong doesn't always equate to longest lasting.
Quality of the build is the biggest factor, assuming reasonable quality parts.
The only place I'd use a Sapin Strong (13/14 SB) spoke is on the rear DS.
Using one on the NDS, with its lower tension is counter productive, since the spoke is under very little elongation at those tensions.
On a front wheel, it's just unneeded weight, since thinner guage spokes are beyond "strong enough" for symmetrical hubs.
