Thanks Cyclic
Both machines have the same Hampajen lines (Not sure of spelling!) that are now so popular in Oz. Have used different lengths 50, 100 and 150ft and haven't noticed any difference in the propensity to spin. Will keep playing with different things but suspect that it may be a slight difference in the cut of the bucket.
Both 214's are going well. Have done over 600 hrs in them now with only minor hiccups. Like all machines if you treat them right they go great. Its a shame that a couple of dodgy US operators of yester year have given the things such a bad name. Theres no doubt that in the conditions prevalent in Oz they are almost untouchable performance wise.
