band saws

So looking into buying a used bandsaw, like a 10" or 12" Ryobi or Delta bench model. Question is the 24 tpi blades for metal. Any issue cutting up to 1/4 inch with these light weights? can I go a little more aggressive or do I still have to follow the 3 teeth contact rule? Jig sawing a 16 inch piece of 1/4 is a chore when your cutting like an inch a minute.
