A friend of mine is try to get into riding, but his saddle is waaaaaay too soft, and it's pressing all the wrong places. He's quite big boned, in addition to being ~300lbs. Any advice on a wide, but firm saddle? He doesn't really want to spend the kind of money a Brooks would cost. I was thinking a cutout would help him a bit. Not sure what his sitbones are, but I imagine he would need a >150mm saddle. Any suggestions?
