Help me decide! Leaf pack questions..I know, I know..

I know this has been beaten to death in so may other threads, but I haven't really found an answer for what I am looking for.

In August, I purchased and installed the OME kit with the 2" AAL from HeadStrong Off-Road. Now, I am looking to upgrade to a new Leaf pack and I have a few questions:

1) I am getting the leaf pack w/ new bushings, extended rear brake lines, U Bolt Flip Kit and Wheeler's SuperBumps. Is there anything else that I will need?

2) Should I add an overload leaf or not? I have seen reports of 3"+ lift in the rear with the overload leaf. I don't mind a little rake but I am curious to know measurements from people who don't have the overload leaf versus people who do.

I don't think I plan on getting the overload. I only tow a 30' pontoon twice a year and the only other heavy item I can see hauling in the bed is a motorcycle. Once, my friends get rigs for off-roading, I will off-road more than tow. For those reasons, I can't see needing overloads. Maybe I am wrong?

3) Dakar vs. Ironman rear leaf pack

I know the concensus around here is that Dakars are AMAZING and in the past, TW hasn't steered me wrong once!

Just curious what people think of them versus Dakars? Measurements? Ride Quality? etc.

Here is a quote from Haslefre's Ironman kit install/review:
"looks almost identical to the Dakar's but with 1" less of lift."

Thanks in advance for everyone's continued help.
