ive grown to like the federal wads for straight wall, use a lot of 12s3 and 12s4. there are clones of these but I always stock up on the real ones when they are available.
there are also quite a few options out there. ballistic products is a great resource for everything shotshell.
for target, skeet trap using Winchester AA and Remington nitro 27 hulls ive used a lot of figure 8 and wAA12 wads. these newer Remington hulls that a smooth rather than ribbed are pretty durable and can be reloaded a bunch of times before splitting
ive probably got at least 20 or so different wads in 12 and 20 gauge so I can put together target or hunting loads no matter what kind of hulls I can come across.
