AMF house...That should say it all but I'll explain...Good bowlers cannot score here. The only people that are bowling decent are the high rev / high speed guys and the straight bowlers. Usually I can figure out a sport shot or a modified shot but this is not a shot. It seems to be the lane machine doesnt clean the backend. There is no back end reaction unless you have very high revs like the 2 handers or the no thumb guys. I used the Guru Master, no luck, Warrior, no luck, Tag, no luck. I played every line possible..Up 5 and it stays outside, up 10 and it hits the 3 pin, move inside and try to swing it and nothing comes back. Only if I throw it 11 or 12 MPH do any of the balls have any movement. Oh, the Jackal had the most movement but it was like split city. I bowl in 3 different houses and never had this issue before. I cant tell where the oil is, the balls dont come back with much on them either. Now the question is...Do I need something stronger then the Tag but weaker then the Jackal? Im med speed, med revs, last year avgd 218 at one house and 207 at another. My feeling is that they dont strip the lanes so I need something to cut threw oily back ends but not burn up before it hits the arrows...Any suggestions?
