GND Filter Select Question

[jianglinxi]

Hi,

I'm using Cokin z-Pro resin GND filter for my landscape shots. But I found the sky with clouds have slightly color cast to magenta by single GND piece.

I'm not sure if Lee resin filter is the better choice than Cokin. Should I choose Hitech Firecrest glass filter to replace resin filter.

Please give me some suggestions. Thank you!
