yes, it does seem like a perfect lapping hone and if I do become one of you honemeister dudes I may need to invest in one, and if I didn't just get this I would have done it but I don't think SRD would take kindly to returning it to say I changed my mind and want to buy this other one you don't carry. It is on Amazon for $90 too. It just makes sense to have the whole hone in contact while moving it around to lap it to be sure it is flat.
Either way I am going to give my 325 a go and see what happens. Will
let you know.
