Good to see you getting out at least Paul.

          That's a bigger perch than I've ever got out of Sylvan.  I've heard tales of the good old days when you could land some good chunky buggers out of there in deep water and have tried in years past but never had much luck.  Good that you're seein some good ones though, eventually on the right day a guy might hit it right where they take without caution.  The whites in there are pretty constant from my experience although haven't targeted whites in a while.
         One thing Sylvan taught me is the value of weedlines.  I used to have a spot out in Marina bay that was in about 12' of water and if you drilled that 8 inches of ice just right you'd be fishing half sand half weeds.  Caught everything from whites to 20#+ pike out of that spot but for whatever reason decided to search more of the lake and found it really moody.  Generally take the family to Gull as the action is more consistent but would love to spend some more time on Sylvan. Thinking late ice would be a good time.
