My assesment of the strength of the attacks of World Test cricket:
South Africa: Pollock, Ntini, Nel, Kallis, Adams would be my attack. Adams is the only one who can be a threat in any conditions, but the first 4 are all capable of being deadly in swinging, seaming conditions. Adams, of course, hasn't done especially well for a while now.
Australia: McGrath and Gillespie are both brilliant in seaming, swinging conditions. IMO Inness, as you know, could be the best of them all. Warne, when returning, is a genious obviously. As for the rest

. That's all I've got to say about that. Harwood's a decent prospect but ATM far too wayward.
England: Caddick is basically the only decent bowler left with a chance of playing again. Don't think much of any of the supposed "promising" bowlers. Hoggard and Anderson are OK in swinging, seaming conditions but not as good as Caddick, Gough, Cork, White. Johnson could be good but still has only played one proper Test.
India: Kumble and Harbhajan are good in turning conditions, pretty useless elsewhere. Agarkar is brilliant in any conditions on the extremely rare occasion he bowls well. The rest are useless with Srinath gone. Sarandeep could be pretty good, far better than Kartik.
Pakistan: Shoaib is a class apart ATM, Kaneria could be similar, Shabbir has had a terrific start to his career and he's been pretty good in his recent domestic years. I rate him highly, but he's no Wasim or Waqar. Saqlain can be good in turning conditions if he ever gets back in the team.
Sri Lanka: Vaas is a genious, shame he's so spectacularly inconsistent. He could have been the second-best seamer ever IMO. Murali needs no comment. I rate Zoysa, Lokourachchi and Dharmasena highly, but none have especially impressive Test records, and Dharmasena's had countless chances. Zoysa still needs some work, but he was good on the A-tour of Kenya.
West Indies: I really don't think this optimism is very well founded. From what I've seen Edwards is quick, has a good seam and tries hard, but simply isn't accurate enough for Test-cricket ATM. Banks is an average fingerspinner. Taylor doesn't seem especially good, though no, I've never seen him. I never saw Brendon Julian, either. Collymore doesn't seem anything special, either. I thought Sanford was useless on figures and nothing has changed my impression in this Test. Why Drakes continues to gain selection I'll never know. His accuracy is somewhat overrated, it's not international standard. Never seen David Mohammed, but just because he's a wristspinner I'd guess he's the best prospect. Really can't comment on Ravi Rampaul but just from all the rest I'd guess he's not accurate enough. I've seen Tino Best and his bowling is an absolute joke IMO. Jermaine Lawson looks like a good one-day bowler at least, but until he follows that seven-for with some more Test performances of note, I'll reserve praise. Not heard much about him except his pace. Dillon simply isn't Test-class, either.
New Zealand: Vettori is the best fingerspinner in The World IMO, but he's not done much of late. On wickets that don't offer seam, Tuffey, Oram, Bond, Styris and any other seamer are a complete joke. On wickets that do offer seam, they're all pretty good, though not as good as Allott, Nash, Doull and Cairns were.
