There's certainly no problem with using Lava/Kusha. Rajas + an Acc ring is arguably better, but still may not be better in all situations (note that prior to the March PUP H2H skill update, Lava/Kusha was a little more appealing to PUP due to our native accuracy deficiency). "Acc ring" here includes a lot of options: Toreador's, Ulthalam's, Iota (particularly if it brings you to an even total DEX, thus adding 5acc), Insect, Sniper's/+1, Woodsman.
Your call whether you like having Tamas more than Rajas. You're right though about the 27 day wait, if you've dropped a CoP ring more than once you need to wait to get a new one.
Hollow/Brutal is the best PUP pair. If you don't have Hollow, Aesir is a great second choice. Could also consider Diabolos's Earring for that second choice, and Fenrir's during the day trumps all Atk earrings (but you have to deal with remembering to use it during the day only).
As people have said, Pantin > Fidelity Mantle (with good augments, from MKE) > Aesir > Bellicose. The first two can be pretty hard to get.
The Salvage gear for PuP is what we should aim for getting and have mix/match of gear for automation buff depending on what we are doing?
Salvage gear - Um... 5/5 Usukane is certainly excellent, but it's pretty damn hard to get (and very expensive to obtain the head/body). Since you rely on getting notoriously stingy Salvage drops, you could do Salvage religiously multiple times a week for a year and still not get your drops, so I wouldn't exactly count on it.
In general, you'll be focusing on Acc and Haste for TP, macroing in appropriate WS gear. The puppet enhancing items are good - all of the relic set except the head are quite useful. Body/hands are solid TP pieces by themselves, and are even better with Sharpshot/Valoredge puppets. Legs/feet are staple pet nuking pieces (and legs are a great TP/WS piece). Other than the Pantin set and the mini-expansion rewards (described below), there aren't a ton of other must have pet stat pieces. Spurrer Beret and Herder's Subligar are the big ones.
PUP can make some excellent armor from the mini-expansion pieces too. I personally used my head/legs solely for the master (WS Anwig Salade, and Acc/Haste Desultor Tassets), but they do have pet stats available. Body is a great master TP/WS piece with Acc+10 augment alone (plus the base STR+5 DEX+5 stats), and pairing it with the Pet Magic or Acc augments is common. Edited, Apr 30th 2010 3:45pm by Anza
