I have to partially disagree with Yancy on the multi-tip line question. While a standard weightforward floater IS nicer to cast, than the floater section of the multi-tip line, it isn't, in my opinion, nicer enough to warrant carrying the four separate lines and spools that one would need to replace the multi-tip line. The Multi-tips are much easier to carry if you think you might be facing varying conditions.

Now, if you know that one specific line is going to work, well, then by all means load that line up. And carrying separate lines on separate spools is certainly an option. But I think the original poster is concerned about cost of the overall outfit, and the multi-tip line is going to be a much lower cost option.

I have three of the Rio multi-tips, on a 6 and 8 wgt, and a 8 wgt spey, and have no complaints. The rods have hoisted in some beefy fish with no line failures, and the lines cast well. The only use I wouldn't recommend for them is stillwater, where a full sink line is going to work better.
