I keep hearing good things about the cherrywood (the peated not so much) so I might try it next time instead of the Weyerman.
All smoked malts are not created equally!
I too had heard peated smoked malt was 'not so good'. I tried 3 lbs of the weyermann in a Porter ... pretty good. Then I tried the same of the cherrywood in a similar recipe, and it was much more flavorful (lot stronger smoke too). Then I stumbled across a clone for Stone smoked Porter that called for 4 ozs of peated smoke; ........ It tasted great, and I am sold on the peated smoke, you just have to realize that you don't need much.
0.25 lbs peated = about 3 lbs of Weyermann or Cherrywood. A huge difference in what is required to get a similar smoke effect. Which smoked malt is used in Tumbler at 1% level? I suspect it is asking for peated malt. For a 1.060 beer, about 1.5 ozs is equal to 1%. If you use anything else, you probably need about 12 ozs.
