Alto,
You should be aware that the Inferno should, in general, be able to handle medium to medium-heavy amounts of oil. The Inferno (and the X-factor recommended above) will approximately as long as the Blaze, under normal circumstances, but with a stronger, more pronounced backend; in fact the Inferno has one of the strongest backends currently available. The Blaze is a ball intended to handle medium-light to medium amount of oil, but its actual performance depends on your release and delivery style.
Also, the amount of hook is not related to a ball's ability to handle oil. In fact, in general, most balls intended for heavy oil will hook less than true hook monsters like the Inferno, which is intended for medium to medium-heavy oil patterns.
A used Inferno, in great shape, (do not always believe an ebay seller about the condition of a ball!) should go for no more than $50-60 delivered to your house, if you are within the 48 states.
A plugged ball should be almost indistinguishable in performance from a new ball, even if 1 or 2 of the plugs are in your track, AND IF the plugging and re-drilling are done correctly. Personally I'd prefer to have no more than 2 of the plugs near my track, but that is my perference. Many people have found balls to perform great even when they have been plugged twice and drilled 3 times. It all depends on the ball and the quality of the work.
