I have to agree with you Ian .....If it aint broke dont fix it. Fender largely got the strat design right first time round.The fact that the design is basically unchanged in sixty years ,still in production and still is the most popular and most copied design says it all. Admittedly the trem design is not perfect but probably 99.5 percent of guitarists never use it at all.There are some excellent trem mods out there for those of us that do use it.
There are scores of hand made and specialist guitars available out there but none appeal to the huge numbers of Strat and Tele players in the same way.
