I've had them streak upstream, then turn and blaze down leaving me with a pile of line everywhere. I'm hoping the LA will help.
Louis,
Because John has already hijacked his own thread with that prurient poster, I'll run the further risk by sharing a few thoughts about the situation you describe:
As I learned long ago with steelhead, the only tactic that works reasonably well when big, fast fish go ballistic and rapidly reverse direction is to clamp the line under your finger and strip like crazy. (And a glove or tape can provide some protection from the inevitable burns and cuts that result from this tactic, whether stripping line in or easing it out to a suddenly surging fish.) No fly reel short of a high-speed motorized winch can keep up with such maneuvers.
That said, the LA will respool the stripped line quicker. Due to the wider spool, however, you might need to pay more attention to winding the line evenly in order to avoid tangles and potential binding caused by the line bulking up in one spot under the frame. I slightly underfill my reels (especially my big-fish reels) to give a margin of safety in this regard, but that practice could compromise the limited backing capacity found on most LAs. These considerations might sometimes negate the advantage of a faster retrieve.
Lamson does indeed build very nice LAs, and they pay more attention to weight than is typical of many LA makers. Many of their reels are great values, and I think you made a good choice. However, I do feel that a few of the advantages of LAs are a bit overstated. (The more consistent drag as line is reduced on the reel is, I think, one of their main advantages.)
