When alot of people see the straight blast for the first time they think its so easy and simple to do and there conclusions to the straight blast is that it has no power behind it which is false. Like in any technique you have to train and develope it to make it stronger and more effective then you will see the true power behind the straight blast when done by someone who has mastered that particular techinque. When I do my straight blast I can hit just as hard or harder then most peoples right cross.
Talk is cheap take it to the pit.
