I am going to keep this to reasonably current players, I don't date back far enough to remember anything pre-2000, although my knowledge is growing...
BATTING
Pull - Ponting, easily
Cover Drive - Hussey's is a thing of beauty
Sweep - Hayden (albeit he got out from it yesterday)
Reverse Sweep - Heard a lot about Jonty Rhodes, so he gets an honourable mention, otherwise Hussey again
Power Batting - Chris Cairns, Matty Hayden and Andrew Symonds, Lance Kluesner
Facing Spinners - Michael Clarke
Overall - Bradman obviously, Gower, Slater, Martyn, M Waugh, and Langer seemed somewhat appealing when in form, in addition to all mentioned above.
BOWLING
Pace - Donald, Lindwall (from what I've read), Lillee, Lee, McGrath, Bracken, Hadlee, Akram
Spin - Warne, Vettori, Chawla from what I saw yesterday, Panesar. (I hate Harbhajan's action, looks to dodgy and cluttered for me)
WICKETKEEPING
Technically - Healy, Boucher, Knott, Tallon
Visually (spectacular catches/stumpings) - Gilchrist, Healy, Boucher
Nice format, will adapt this in my choices as well. My selection is based on what i've seen live, on footage & what i've read.
BATTING:
Pull shot - Ponting hands down currently while Richards & Richardson seemed to be savage pullers back in the 80s & what makes them even more special is that they did it without helmets.
Cover Drive - Hussey currently for left-handers, Vaughan & Martyn for right handers, with Lara & Sobers with there caribbean flourish definately just as good.
Sweep - Hayden for power & Lara for his ability to hit them exactly where he wanted his battles with Warne & Murali especially were stuff of legend.
Straight/On-drive - Tendulkar without a doubt in modern times & Richards back in the days.
leg-side play - Azharuddin, M Waugh to watch these two blokes play shots through the leg-spin were just majestic.
Cut shot - Lara, Gilchrist, Gayle & Sehwag just savage when in top form.
Reverse sweep - Flower, KP, Rhodes are the best exponents of the shot that i've seen.
Power batting - Symonds, Freddie, Cairns, Afridi, Klusener, Gayle, Hayden, Gilchrist
BOWLING:
Pace/Swing bowling - Donald, Lillee, Akram, Lindwall, Akhtar, Thompson, Bond, Waqar, Holding, Ambrose, Hadlee.
Spin - Warne, Vettori, Laker (on footage looks to have had the perfect off-spinners action)
WICKET-KEEPING:
Technical ability - Healy & Richardson from modern times, while historically Knott & Grout.
