A spey guide or a bar guy would probably float down from Scale Bar being tossed by the ruthless bottom bouncers there.
Seriously, I have not been to Scale yet. The river level is pretty high this year. Do you need a wader just to cross the usually dry inside channel and get out to the bar?
I personally prefer Scale Bar over Peg Leg in early season. Peg is not accessible now unless you have a boat. Later season, the lower section of Peg is just too unreal with a sea of people and rods & lines crossing each other. The mid section has slow & shallow water, so it is good for fly fishing. The upper end of Peg used to be a good spring spots. At high water like now, Scale Bar has a long stretch of productive water but later when the mid section is too shallow to fish, you have to wade out sooooo far in order to fish effectively and folks have to stand waist high. Not my liking for summer fishing. There are other bars besides these two, such as Seabird, Jones/Laidlaw, even the infamous Snaggy Bar (if you don't mind losing betties faster than you can tie up).
One more thing is, when the river drops a lot later season, there are so many formerly submerged bars available. There will be no need to jam into these gong shows. Just explore & you will find peace & quiet, and still be productive.
One last point about people not wanting to respond to the Scale Bar question is probably due to the mind set of some members of this forum. No one wants to invite ridicule from anti-flossing folks. To admit that you have fished Scales can bring unnecessary ridicule even if your intent is just to share info. Most cannot PM each other (not a subscriber) even if one wish to PM the info to the poster. But it is also quite possible that most people have not started fishing the Fraser yet. The high cost of gas & unpredictable result of targeting springs have made many of my fishing friends staying home, or fishing more locally, like the Cap. If there is an opening of sockeyes, all hell will break loose and the bars will be jam-packed. The latest test fishery numbers are good. So keep your fingers crossed.
Good luck fishing.
