2 handed Bowling with polyester

Hey guys, I’ve recently started taking bowling a bit more seriously. I got my first polyester ball and have been trying out a few techniques. So far, the two-handed style seems to work best for me and has the most potential. For spares, I still use the one-handed technique for better precision.

Now, here’s my question: I don’t want to spend too much money on a hobby I just started. Should I continue bowling two-handed with the polyester ball, splurge on a reactive ball, or stick with learning the one-handed method?
