[NSRCA-discussion] 50 Size SYNERGY

[Bill Markovitz]

Matt...........Thanks for the input.  I use the same
trimming technique with my other models.  7/16" may be
all I need to get rid of most of the 4 oz. of unwanted
cargo.  I haven't weighed the model yet, but I have a
feeling that it is going to be on the heavy side.
