Cory Wallace's take on SpiroTiger

I asked Cory what he thought about his first year using a SpiroTiger.  This is what he had to say:

After some speculation I started using a Spirotiger last June during race season as suggested by Luke Way at Balance Point Racing.  I used it 1-2 times a week for about 20 minutes.  I noticed improvements on the spirotiger but it was hard to judge on the bike.  I was curious though to see what it could do if I used it regularly.
