[Healeys] vinyl top advice

[Charles Rice]

I want to order a black top for my red BN2 while they are on sale this week.

I am considering the "Everflex," "English Vinyl," or "Crush Grain Vinyl."
The car

Is driven mostly in warm months so the top will stay down most of the time.

I would like advice from owners familiar with the different types - would
either

of the two cheaper ones be adequate?  What's advantage of "Everflex?" 

Thanks - Chappy Rice  BN2
