Pook. Excellent choice on the composite shallot. SPX has done the exact same swap and there is a thread showing it around here somewhere. the blade and handle of the composite shallot are thinner than the black shallot. remember that the only parts from the black shallot that you will use will be the handle slabs. the screws, washers, blade, and spacers will all have to come from the composite shallot.
happy modding!
