a comparison was done with WO bars a few months back and gen they are identical, despite the hatred for mr slimeball i ordered them from him and they seem decent enough, even surviving many reinstalls.
as for drilling lug holes its a piece of cake with the proper vise and a drill press. i use 1.25mm carbide bits with a 1/8 shank 1.3mm looks too lare and 1.20 wont allow the pin to poke through if its not perfectly straight, 1.25 seems to allow such clearance while remaining true to the original pin hole. for the bracelet and end links i use a pin vise and a 5/64 bit working the bit through the existing hole by hand via the pin vise, never had a problem with this method, the hardest part for me is re polishing the lugs back to factory shine, its more of an art.
one thing ive noticed on gens vs our reps is that the springbars poke out of the holes like a little button, im assuming this is from polishing over and over again wearing down the case?
the setup takes the longest time, dont rush that part, use 3in1 oil slowly work through the case, take your time, expect to break a bit every 3-5 holes
the end result is worth it
