' isinglass ' material ?

[abl1111]

What a confusing topic this is ! I'm looking to replace the clear glass on my hardtop enclosure ( 23' Tsunami ). I'm not sure what is on there now but it's not clear enough for me.

I'm looking for VERY clear stuff ( I hate enclosures due to visibility issues, but like being out of the weather ) that needs little maintenance I am not planning on rolling it up, although, having it zipper up and out of the way is an option. If I can get 6-8 years out of it - great.

I've read online about the many different materials, the pros and cons - it's dizzying.

Who has something that they really like and it has stood the test of time.

Thx
