irega hands down, used to use bahco of all shapes and sizes but switched to irega when bahco moved production out of sweden. my personel favourites are the irega 77 series, solid with no side movement and keep the set size. the 12" model is good up to a 28mm nut and the 10" model will do a 22mm nut, also got the 15" set which is handy for extra leverage (but being 18 stone rarely needed) the 99 SWO is the same design as the bahco 8" wide jaw but i prefer to have a longer handle. as a side note irega make adjustables for chanellock, kingdick, britool, hazet and previously rothenburger before they decided to abandon quality for volume.
