5 hit is a bit more reasonable these days, but I'm still not sure if it's worth the tradeoffs. If I were going to use a 5-hit set, it'd be something like this:
That should grant a 20.3% TP per swing return /SAM, leaving you needing to WS in 26 store tp to have a true 5-hit (landing extra hits on drakesbane will allow a bit more wiggle room). Of course the tradeoff is you're sitting at 24% haste, have to use ace's feet instead of lancer's +2, hagneia instead of thew, and you lose the 7 polearm/20 attack off lancer's +2 head.
