The venom blade looks very nice in the tx

Rare id imagine doubt id ever get hold of one.
The lower main sear looks longer on the mach1 compared to the cd so obviously more room to shunt the pivot forward, beautiful workmanship,the 'unsprung' weight of the lower main sear will be less too as its thinner,less mass less force to move it
There is a few mm left in the cd to gain by the looks of it

one of my cds is hovering around 10 oz after a polish up,so lord knows how much more could be shaved with a shift in pivot point!!
