In Casey Walkers(wot 455) own words taken from the Realoldspower websight :

"I am running his 5 main halo as of the beginning of this season
with no issues. Sitting right at 70 mid 11 second passes as of
now. He did all the machine work for me. Jim is a nice guy and
has attention to detail. His stuff is nice and his prices are fair."
