I have the exact opposite of your story with built yotas on 38s and 40s sturggling on rocks where a 33 13.5 15 ltb on a yota walked right up. To each his own but i personally love the LTBs and have also had numerous TSL set before LTBs. What i really want to try is the PB rockers. Oh and as far as dependability how is that ford tranny? Oh and i could get into your 4stro "knowledge" but i'll save that 
i really like my 34" ltbs. tough tire!
