Well if you want to stay shoveling, I'd recommend something like a slingshot or even another tropical storm. If you want to change something form-wise, I'd recommend trying two-handed, it's a lot easier to be consistent than no-thumb one handed.
If you want to try bowling 'normal' with the thumb, I'd recommend a higher end ball like a nano or a nexus.
Overall the best way to go is to ask your pro shop guy what he thinks.. as he can watch you bowl and give you lessons and such.
