I don't bowl at 140 kmph or 150 kmph, so my best chance of getting the batsmen out is by bowling in the right areas and getting it to swing.
I could bowl really fast and as the years went on I started to develop more skills - I learnt how to swing the ball a little bit, use the crease a little bit more. But I knew what my skill was and that was to run in and bowl fast.
It's a privilege to be on the same field as guys like Jimmy Anderson and Stuart Broad when they catch fire like they can do. Two of the best there has ever been.
The start of the English county season - from April to mid-May when it's cold - is the same as South Africa because it seams and swings. After that, the ball starts spinning nicely, and that's when I get my wickets.
I like to watch batsmen who will entertain and, as things stand, an opening spell from Jimmy Anderson is about as good as it gets.
What you can never do on a slow pitch is bowl with any width. If you bowl straight it's almost impossible to get the ball away.
In T20, I think it's really valuable to have a bowler who can bring the ball back into the right hander at pace.
An out-and-out fast bowler is one of the great sights in cricket.
Roland-Jones is a good, old-fashioned English seamer. He's not especially quick, but he pitches the ball up and swings it away, which is always dangerous.
I don't want a new ball when I am bowling in the subcontinent. I want an old ball that can't get hit out of the ground. I want a ball that when I bowl doesn't have true bounce, so that the batsman can't hit it.
When I bowled to batters like Michael Vaughan or Jacques Kallis who were classical, technically perfect, sound batters, I always found that I could get them out.
I have always been an attacking bowler, but I am trying my best to learn every day.
I have so far enjoyed my preparation with red ball cricket. The Duke ball swings a lot when you're here in England, and initially, when I started playing here with India A, I realized that the swing will come a lot into play in these conditions.
I try to keep the ball up to the bat, and I usually get the ball to outswing, so I get wickets like that.
The thing I've got to concentrate on for South Africa is bowling at good pace and if the ball is in the right area that will cause enough trouble.
When I made my debut in 1994-95 I bowled big outswingers pretty much every ball, because people had told me you should bowl consistent outties to take wickets.
There are two bowlers who I think are very tough to play against - Dale Steyn and Morne Morkel.
What we have learned is that Roland-Jones is a very promising prospect. Because of the way he bowls, he will not blow batsmen away, but is more likely to take wickets through accuracy and building pressure.
The history of Test cricket will suggest if you hold the top of off longer than anyone else you will have success, in England particularly it's about owning the top of off.
Bowling in sub-continental conditions is not easy for a fast bowler. You have to be consistent and persistent to succeed, especially when you are bowling to the likes of Sangakkara, Mahela, Samaraweera, and Dilshan.
I love watching Mohammed Shami and Umesh Yadav steam in. They both are sharp, possess good pace, and swing the ball - making them lethal.
That is one of the great things about Test cricket, the ball. Sometimes it swings conventionally, sometimes it doesn't and sometimes it reverses.
Those first few overs are obviously the most difficult time because you don't know what the ball is going to do in the air and off the seam.
I might be six foot six but that doesn't mean I can play a Steve Harmison role and bounce people out.
If you are good enough to play international cricket, you can take wickets - but you have to bowl the right length.
