Newmans haven't got any plus points in the yb cams,
As Kent's and pipers are more experienced, and there isn't issue's on the cossie setup like the CVH.
I run piper cams in my cossie.
Had a RST in for some work this weekend, and its had a piper T2 cam fitted a month or so ago. and about 300 miles.
And its fuc-ed, dont know if its the cams fault or if it weren't fitted correctly.
