Summons: Good vs. monster with DR?

[Fanaval]

We know that treantmonk has magnified the quality of summon spells in his superb guide to the wizard. The problem is: a wiz with augm summoning is effective if he face a monster with damage resistence. For example a wiz 6 lvl that face with a leopard a cr 7 or 8 monster with DR 10. it seems quite uneffective because the leopard has damage 1d6 + 5.
Any toughts?

Summon a grappler instead. Let the meatshield pull out the right material for DR and SHAZAM.

Lantern archons become available with summon monster III. They have ranged touch attacks that overcome all DR. Dose to desired effect.
