It's funny because I normally hold the wheel such that the thumbs hook over the bridge of the wheel at the 9,3 position because it's accurate that way. I'm currently using a Logi DFGT wheel which has those protruding lumps at the 11,1 position. I find that after several laps my thumb becomes quite numb and if I just hold it at the 11,1 position, my hands don't cramp as easily and that turing actually becomes easier. I'm just wondering what most of the ppl here hold it as: speed-wise and endurance-wise .
