Slmz,your batting avg is very impressive. With regards with whether you should bowl spin or fast/medium, which do you enjoy doing? Which are you better at according to your stats? Can't you mix it up? Also you should try to find about your opposition, maybe the last few times you played, they were good players of spin & that's why you couldn't get wkts. If you see a batsman is struggling against spin,bowl spin,if not bowl fast. Depends to which batsman you bowling, sometimes the middle order batsman are good players of spin as compared to the openers,if that's the case,ask the captain to give you a chance at another position bowling. You have to also analyze your situation & focus on your strength with your bowling and also work on your weakness. As you are a fan of Afridi, i would think you'd want to bowl spin- if that's true watch video clips of spinners and try to implement and see what you good at. Sometimes by trying out different deliveries you might be hit more runs but you'll figure out the batsmans weakness & dismiss him,it seems like you are a very defensive bowler,i might be wrong but if so than be more aggressive and attack. You need to decide what you want to bowl & concentrate on that. Hope that helps.
