Unhomed,
Let's see if we can help.
When you stay spin do you mean you are spinning the ball? Not staying under it I assume. It sounds like it's bowling technique flaw and not the equipment. Not sure until you can explain better how you bowl and your technique. Give us some starting points. What board do you slide on, ball trajectory, ball track and flare (where does the oil on the ball go around the ball), your stats. age, which hand, approx ball speed if you know, etc., how long bowling and average, who drilled your equipment and how it's drilled..the more info. you give the easier it is to help.
The best would be to see some video if you have the ability to do that?
