Hi, I'm looking at getting either a Walker Bay generation 11 LTE which allows for a 30hp engine and is made out of fiberglass bottom or a Highfield 360 CL Delux (new one is beautiful with diamond upholstery) which allows for 40 hp engine but is made out of aluminium. Both Hypolon RIB. Anyone with experience with either fiberglass vs aluminium? Also like the Zodiacs 360's which also allows for a 40hp. Thanks!
