I have always wanted to fish Havasu. It's on my bucket list. A good friend of mine Fred aka Rionator has fished Havasu several times and has used a guide. He was catching Redear two plus pounds and over. I do not know the guide he used but Fred now fishes that lake without a guide. He stated it is well worth the trip!
Side Note: I can try to get you the guides name that Fred used. Hopefully Fred will respond to your post also.
