Now just a few weeks ago people were saying the 60 would work fine,now that they've said something about the 70 your saying the 60 isn't?I believe ,from what others have said about the 50 that the 60 will do good.I don't think it will be to overly torquey like a 1515,but will get the job done nicely.Now if I've missed something lately,please forgive me,but please inform me so I can get it right.
