Getting ready to purchase these seats because they are one of the few affordable seats that fit my FD. Biggest issue I'm having is will I fit? I'm 6'2 235lb, my waist is 19 inches across. Biggest issue though I'm worried about is my shoulders, they measured 23 inches across. Any big guys have these seats? The shoulder area is 21.5 inches with the bolster. Also anybody have experience with them shaving the bottom side of the bottom cushion? I'm just wondering if these seats will be comfortable. Any help much appreciated!
