Having made the "Big Strake" modification already I
can say that:
1. the bigger strake sections don't
look that funny hanging off the doors
2. the longer
strake section on a comfort basis is most effective because of
the additional height its gives you at the armpit area than the length
of
the arm rest. Simply extending a non-big strake
setup so there is a longer
arm rest portion will not
give you any additional height.
I will dig up some
pictures of the doors open so you can judge for yourself
if they are ugly or not.
