stringer vs weave

Hello all

For positional welds like 3G / 3F - vertical upwards, how do you choose between stringer-bead and weave?

For those of you working to WPS's (Welding Procedure Specifications), do the WPS's you meet normally specify?

Recently with E81T-1 (Rutile Flux-Cored Arc Welding), 100%CO2 shield (as recommended for the consumable), I've preferred stringer-bead for low heat input therefore toughness and found smoothest surface that way.

For what it's worth, I found 215A 26.0V good, and I found the more experienced welders were using that condition anyway (the machines' voltmeters where all over the place, but put my meter between the wire-feeder and the plate and that's what you found) - but usually weaving not stringer.
