I've met Mark a few times as well. He is knowldable, but the ego and sometimes arrogance can be overwhelming.
On a side note there is a man that is extremely knowledgable and very modest. He is always willing to give good, sound advice based on his own personal experience. If you want to learn about a fishing topic and get great advice, speak with Tom Greene from Custom Rod & Reel in Lighthouse Point.
If you are looking for advice in Saltwater fishing call on him (954) 781-5600.
I have dealt with Tom for nearly 20 years and he is a solid source of not only great information but also quality products at his shop. I would highly reccomend him. It is due to his insight and honesty that has kept me coming back to his shop year after year. When he offers his insight I shut up and listen.
