Aldur Summoner Qs and something on Uber Trist

So I'm collecting perfect pieces for each classes set and building a character around each set that can stand on it's own in Hell. Had a tough time deciding on Aldur since it doesn't really standout in any area in particular. Decided to roll with a summoner due to Fireclaw not very effective against FI.

I'm building on Were-Summoner, maxing wolves/bear/HoW, rest into shockwaves (glowing bear just look damn awesome )

So I was thinking, to counter PI, I have these 3 option on merc build. I don't plan to switch weapon for PI.

A1 fire merc Build 1:

Upped Witchwild String double Sheal

Treachery

Any LL helm with 15IAS sockectd

This gives 100IAS to reach 10 frame attack. I'm hoping she'll trigger Amp regularly with this build, hence dealing with PI.

A1 fire merc Build 2:

Faith

Unknown

Unknown

So this will give me fana for my summons and merc itself will deal with PI. Armor and Helm depends on how much IAS i can obtain to hit fastest frame.

A2 might merc:

Eth Reaper's Toll

Unknown (prob just the standard eth fort or shaft or leviathan etc)

Any LL Helm (andy/tals etc)

Decrep to deal with PI?

Discussion

Ok, so I'm just wondering if any of these builds are viable. Will the build 2 merc's fire arrow be enough to deal with PI? Will build 3's decrep be enough? Any other suggestion to deal with PI?

Off-topic Q

Just an off-topic question. Does Slow Target and Holy Freeze work on uber trist?

Any input is appreciated |||as for build, it should be ok since it's not really affected by the weakness of the set.

imo if you go for merc-reliant PI solution, i'd say go for reapers. it triggers so much more frequently and faster..|||Reapers by far imo.

And yes, IIRC.|||I did some numbers on IAS, it seems both build 3 and build 1's armor/helm can be treachery/ias helm to reach last achievable frame.

Think I'll try both and see which 1 is more effective then. The thing with reapers is that A2 mercs are melee, often with summoner builds you get so much meat at the front, they usually get stuck in narrow maps. :/|||Then simply resummon your minions behind the enemy and get some flanking on
