Mage Trinket

Hi, Currently I had

1. https://www.wowhead.com/wotlk/item=5...adins-spyglass
2. https://www.wowhead.com/wotlk/item=5...ng-ice-crystal

and planning to buy
https://www.wowhead.com/wotlk/item=4...of-the-heavens

what is the best combination of trinket for arcane & fire mage ?

thanks

For Fire Mage, though I could be wrong..

https://wotlk.cavernoftime.com/item=50340 and https://wotlk.cavernoftime.com/item=45518.

https://wotlk.cavernoftime.com/item=50340 in essence gives you 131 crit rate (2.85%) and 180 SP.
https://wotlk.cavernoftime.com/item=45518 provides 120 crit rate (2.61%) and 850 SP proc.
https://wotlk.cavernoftime.com/item=50259* provides 111 SP and its use for few increased chances of crit.

*The tooltip is wrong, the initial crit rate boost should be 920 (20.04%).
