Well john i have had 682x which i shot very well at Dtl and sort of ok at trap and had a dt x which i could not get on with at all. Both were bought to try due to a neck / shoulder injury from when i used to fence at least i think that's were i damaged it. I wanted a more upright head position anyway i never fully settled and then the problem subsided so i went back to standard rib. They are comfy to shoot and you do get better vision of emerging targets but on fast trap i found them difficult as when you missed you didnt seem to be able to tell were or why, very strange. I think you have to shoot them for a good year or so before wet settle with them and i am not known for my patience. .. Anyway the last week or so the old neck problem has emerged again maybe because of the colder and wetter weather i don't know anyway its got me thinking long term again about trying high rib but this time would have to accept it will take a while for the transition. Wont be getting rid of the eell but might chop my standard dt in which is a bit high in the comb anyway.
Only a thought at this stage.
