I also used a lightning wolf for my exploding arrow amazon. Telash did fairly well but he had a crescent moon sword which is fairly powerful stuff for a mercenary.
The (few) people that have used iron wolves and described their experiences seem to generally agree on the following points: Cold wolves are the best because they freeze and they use focused and consistent attacks. They are the most reliable and most effective despite the lower damage numbers. Lightning wolves have the best damage but the charged bolts scatter so much so they don't focus that damage, making them less effective. The fire wolves are the worst, with inferno not only being useless but also making those mages wander close to enemies to get in range which then forces them to flee immediately after due to their skirmish ai.
Personally I see cold wolves having damage potential and lightning wolves can work too, especially thanks to crescent moon, if you have a built that can capitalize on their charged bolts, like area effect or area poisoning attacks of your own. Wilhelmina may actually be able to make a lightning wolf work because she can freeze the enemy long enough for him to safely bolt them at close range. Fire wolves are hopeless, with inferno ruining their damage and behaviour. The only good thing with that is if you actually want them to wander closer to the enemy if you use them as a defense...how fortunate that Wilma is doing just that and has her mighty hydras to deal out all fire damage she needs.
