Cold-Honed vs Elven Immunities

[Obsidian]

I am playing a half-elf synthesist summoner in an upcoming Reign of Winter campaign. Which of the two racial options will I get more milage out of?

Cold-Honed:

Snowborn can move through natural snow and ice at their normal speed and gain a +4 racial bonus on Fortitude saves to avoid nonlethal damage from cold environments. This racial trait replaces the elven immunities racial trait

vs.

Elven Immunities:

Half-elves are immune to magic sleep effects and gain a +2 racial saving throw bonus against enchantment spells and effects.

How does icewalker compare to Cold-Honed?

You will run into cold, and you will run into witches who may have slumber hexes. Cold-honed is better than icewalker overall, but I would take icewalker, keep your elven immunities, and use a summoner spell for endure elements.

Would ice walker help with snow or only ice? Would I still need snowshoes?

Bump for more opinions.

Also are large mounts effected as severely as medium characters by snow and ice?

[GM_Solspiral]

It is an argument of which situational race trait is better. The reason no one is replying is because it is largely dependent on your GM and campaign. Personally my GM would be more likely to throw a sleep spell than a snow drift but then again we might one day play Reign of Winter.

Well the campaign is reign of winter so snow is a given.
