Rubel has played mainly top flight opposition, whereas Rasel is more with the like of kenya and Zimbabwe.
really? how about Rasel's performances in debut against Sri Lanka, WC 2007, first ever T20 WC etc? he has time and again proved that although limited, he is a very intelligent bowler with the abilty to build pressure on batsman with tight economy rate and force him playing the bad shoy (esp if pitch is slow and swinging) who can bat a bit. With all the experience, he is my ideal pick in limited over matches with Masrafee & Shafiul, if fit. Rubel is an inconsistent fast bowler who often goes expensive and still quiet a luxury for BD cricket in limited overs, although he will keep getting his fare share of games with fitness issues of other pacers. Hope his all round bowling improves like his slow bouncers (thanx Ian).
As for the test format, I completely agree with you- Mashrafee, Shahadat and Shafiul is the way to go.
I have high expectations from Shafiul as our future face of pace.
