"BOB XL has a lot more striking area than the old BOB. He can take any number of punch & kick combinations. I like the more natural abdominal area, great for roundhouse kicks to the ribs, also lower kicks to the thighs. This combo deal was an opportunity to utilize a base from an old BOB that was put to rest after 30 years or so; the Wavemaster top fit perfectly. Great combo deal."
