Icon aal or new leaf pack?

07 Offroad... boat trailer tongue weight 250lbs. Getting icon stage one coilovers and rear shocks... was planning on getting the full leaf pack but installer thinks better off getting the leaf recall done (2 leafs and a overload) , taking the overload out and installing the icon 3 leaf aal. My worry is right now i have the oem 2 springs with overload and a cheap one leaf aal and when the trailer is on the hitch the back end sags at least 4". Do you think the new icon aal or the icon leaf pack is a better choice? I've read without the overload leaf I might be back to the same problem. Any help would be appreciated.... Thanks.
edit: installer kinda made it sound like the full leaf pack wouldn't be a good choice for towing the boat... any idea why? Boat is a aluminum 15' Smokercraft Alaskan with two Tohatsu's outboards on back and a lot of gear.

 

OEM packs suck, the icon AAL is the best kit and will do you well with the recall springs, but for long term a deaver or dakar pack is more ideal.

Both are going to do you fine, the recall springs are better than the old 2+1's, and you have very old springs so they sag naturally.
