i've done some searching and can't find much as far as a comparison between the different brands. mainly, i'm looking at trail gear vs maarlin vs all-pro. all pro and marlin has fj80 rod ends, trail gear doesn't list what there's are. all run .25" tube. All-pro's arms look a little beefier at a glance but its hard to know from pictures. is the all-pro or marlin kit worth the extra $$?
