I am strictly going by what I have heard, but according to some the white hots aren't any different than the triple 7 pellets except that they didn't add the charcoal color. I agree with Dave and Nimrodder on the 209 conversion. I have kept my wolverine and my mk-85 as they were originally designed, to use #11 caps. I can't shoot pellets but I don't want to anyway. I have heard others that like the 209 conversion.
