made my first drift on the sulduck this spring at 300 cfm. met the canopener. got that first ding out of the way. by the way a guide i've used several times over there felt i'd have no problem. good thing i had a long time freind along who is also an adventurer like myself. my gudes wife was impressed we made it to say the least. have made lots of trips since. the hoh,skykomish,cowlitz,green,snohomish to name a few. like the guys say take it to the lake first, and work on the turns. hoh is good at 2000cfm and below down to 900cfm. sky is a good float. cowlitz you must deal with the sleds but it's a peice of cake have done it in the dark. green(dawamish) is ok in the spring. snohomish plan on ROWING. love to hook up and share shuttle.
