Bad idea #1?

I just started getting in to bey blade again (and at 16 years old, it's kinda odd for me), and decided to buy two beys, just to keep myself entertained. However, after a while, a standard Dark Wolf and Storm Pegasus (all they had left!!!) gets boring. So, I decided to come up with different combinations and came up with an obvious combination.

Storm Wolf 105 FS. The stamina has really increased, however I am wondering if it is really that great of a combination. Considering that the only thing I have to test it against is a combo of the spare parts, I can't get many different test results. I'm trying to find a Perseus, Fireblaze, or Eagle in the local shops like Walmart or Target, but to no luck. Perseus might not even be out in America yet.

Anyways, is this a good combination, or are the spare parts just weak?
Ask about this kind of thing in the Build Me a Combo! #2 thread.
