I will be trying fly fishing on the Kenai this summer and want to know if a 7 or 8 wt. rod will be good enough for the reds. If so would that also be a good all around for steelies and bows? Also, I am a complete novice to this so can someone tell me what the difference is between a tippet and a leader? And what are some good knots to use when connecting the line to a leader...being an engineer I like my Uli knots but if there is something better please tell me. I seek wisdom. Thanks!
