Best Totem Spells for Templar?

I'm currently playing dual totem, using Frost Bolt totems.

They're pretty decent, although I only have 3 link atm.

Are there better spells than this? If so, which ones are best?

Depends on what your trying to do. Single target boss dps, or map clear speed. Which ever spell or attack you choose it should utilize the same passive skills you would use for your main attack/spell. The question as you stated is overly generalized and a well thought out reply would require more information on your part. However I will venture and opinion, Arc totems seem a good choice. The arc damage bonuses are based on the number of chains left. This makes a decent choice for single boss dps and also has good pack clear speed. What was your ascendancy choice?
