I use to have one many years ago. Best I remember the TM1 special shot at a higher poi. Anyone remember?
I do what ever has to be done to get them to shoot at least 80%, prefer 100% so I make the changes needed to get it there, usually an adjustable comb ... I do not worry about the beads being stacked if I can get it to shoot high enough they do not matter ... I had an early import TM-1, not a special ... WPT ... YAC) ...
TM-1 Special has a different rib higher in back lower in front and a tapered Rib, wider at back tapered in front, Narrower, I owned a TM-Special and I noticed the difference right away. GB................................DLs
