Not sure I attempted to give you anything to use other than a 13 year olds opinions which from recent experience is not always the most reasonable or understandable for that matter.

I think his reference to sharp & blunt was more inline with style and about being cool verses the opposite.

As for his opinions on the other designs, I'll encourage him tomorrow to get an account here and you can do battle with his opinions yourself, and probably the other 10-20 sailor friends of his who will no doubt join in. Beware, their spelling is terrible and its easy to get serious eye strain trying to figure out what they mean.
