Mercon V vs. ???

[Punisher]

Ok... I did a forum search and couldn't locate anything so I thought I'd post.

Current Setup:
S&B CAI
Granatelli COPs
Troyer eFans
Troyer Underdrives
Banks Torque Tubes
Banks Monster Exhaust

I have the Gryphon tuner but only have the canned tunes as I'm waiting on custom tunes to be written.

I've order and received the Troyer Valve Body upgrade for the 4R75W transmission and was wondering...

Is there a better ATF to run than the Mercon V? If I'm going to drop 10qts (according to Troyer they say purchase 8 - 10 qts to fill tranny back up after swap) out of 14qts, I think this would be a good time to make the change... if possible.

Anyone running anything other than the Mercon V in their 2004-2008 F150?
If so, what are your results, thoughts and opinions?
Also, anyone recommend the +2qts added capacity pan? Is there a benefit adding 2qts to 14qts? (about a 15% increase in capacity)

If so, how do I get the last 4qts out of the transmission? Is there a pump/vacuum procedure?

Thanks in advance for any helpful advice!
