While I'm not suggesting that what we're talking about here is in any way the same, it reminds me of what I was once told as a young motorcylist when I was trying to work out whether to buy a Bell helmet or another,unnamed) cheaper one.
My dealer was a guy who had a load of road race experience, including a couple of TTs and several Manx GPs and whose son went on to be one of GBs premier road racers. His response was, "Well son, fifty bob helmet, fifty bob head"! I bought the Bell
Cheers
