thanks again guys for the advice, thought I would report....
we ran browns canyon mid day on Sunday at 3900 cfs and it was sure fun and the water was beautiful and powerful, it was read and run and not technically difficult, that is until after Hecla....I hadn't scouted anything and so didn't even consider stopping to scout Seidel's, couldn't see it all from above but a ledge hole to the right and a lateral on the left so it seemed a center run was the way to go, and it was a fun drop - right into a big exploding reversal wave
we had no chance, flipped instantly in front of 30 people or so who were scouting. Thanks for Colorado State Parks having two very nice and helpful rangers there in kayaks. After we got the boat to the shore and upright we walked back up to take a look at the hole and saw two other rafts flip, some very nearly flip, and then the most veteran river guide on the ark (Dan was his name I think, 71 years old, 40+ years on the river) run a beautiful clean line just right of center....nice....I learned something for sure! At the takeout he and the other guides were laughing at us and saying thanks for the "spectacular" flip as they had all been scouting and watching us and it made the paddlers listen well and paddle harder when it was their turn
on a side note it really really sucks trying to fit an oar rig under the stone bridge at that water level, we scraped the concrete and said hi to many spiders in maybe the scariest part of the float....yikes
