What clutch to install????

Hey fellas, So my southbend MU G56 CON FE clutch has started to slip on me at higher RPM's I installed it 12 years ago and about 80,000 miles. I'm just trying to figure out what clutches you guys are putting in these days is South Bend still good to deal with they were good to me back then, Also which clutches you guys would recommend, I'm not planning on adding anymore power and very rarely go above 3 on the edge, I tow a 5th wheel and occasional dump trailer. My SB has always jerked like crazy when backing up usually always have to put it in 4wheel I would like to see if i could get away from that.
I have called and talked with several different companies and vendors and there suggestions are all over so I thought I would see what you guys recommend

Thanks in advance

I use SBC on all my builds.
The CON FE does "bite" a bit stronger so backing up can get "hoppy". Try not to ride the clutch when backing up will help.
The lower HP rated SBC will not bite as hard, so depending on how much power you are making, maybe the CON O could be a better match. It would help with the smoothness when backing up.
I have been installing a lot of the CON O version in my daily driver 1st gens.

I have the CON FE in my a few of the higher HP rigs and usually in my Tow Pig that sees a trailer following it around often.

Thanks for the reply Oliver, I was looking at the Organic ones just not sure if it will hold up for my towing? Definitely would be awesome for daily driving though.
I've been looking at the Southbend G56 OFEK looks like it would be in the middle of the two?
Also has anybody used Phoenix Friction before I was looking at there clutches and called them up they were super nice and knowledgeable just haven't heard much about them .

Thanks

I have the South bend G56OK-HD in mine and so far about 80k miles of trouble free service. And not all easy miles!
