Suffix Siege is not a "floating" line. The term "floating" is somewhat misleading with mono anyway. Some lines are designed to ride higher with greater surface tension, but mono does not inherently float, although it does not sink as fast as fluorocarbon either. Siege does have a nice slick hard finish that mends easily and keeps it cleaner for greater surface tension and a higher ride though. If floatation is a big issue or needed for hero drifts, try cleaning line or treating with floatant or fly line dressing to increase surface tension.

Even so, I've found "floating" line quality, while desirable, to be more of an issue with spinning reels, and not as much with a center pin reel due to the greater line control and direct connection the center pin reel provides, especially when used with rod lengths you are talking about.

Speaking of rod lengths, 13' is getting on the loooong side for many of our steep gradient, tree-lined NW rivers, especially if you beat the brush or fish from a boat. I have some wonderful 13'ers, but I find them claustrophobic and not as effective on most of the peninsula rivers I fish. IMO, 11'3 or 10'6 are generally more manageable and consequently more fun on most westside coastal streams. Unfortunately most stock "CP" rods at these lengths can be a bit underpowered for big salmon and large native steelhead. Good news there are alternatives available now and on the horizon if you want more power in a shorter rod with good castability. Consider switch blanks in higher powers if necessary or wait for returning NW archetypes like Sage 3106 or 3113 to reappear. Hopefully more choices will come as center pinning continues to increase in popularity.
