Salix Alba Caerulea is already a hybrid and genetically altered for sales i.e a whiter willow as opposed to performance. A great performing bat can made from Salix Alba but it is limited run wise. I've had a salix alba cleft but it is still to be used to confirm it's longevity.
I would agree with most things that have been said.... Pitches do favour the batsman nowadays and that is based on the spectacle of cricket, TV sales and marketing.
Willow growing has been the same since they started Farming willow. You still get good growers of willow and bad ones. Good bats are made from willow sourced from good farmers, poor bats are made from willow that has been left there in a fairly feral state.
Innovations with regards to handles and bats is due to a greater understanding of what makes a bat perform. Law 6 has gone someway in trying to limit this but has left some things open.
Soft pressed bats are really no different to having a bat made from Salix Alba - even with a soft pressed bat you still need to work the bat to get it perform. You still need a stiff layer on the face but you have the springiness of the soft layer. Something you do not have with a bat that has been pressed for the greater market due to returns.
There is no real difference to W G Grace or Tendulkar giving there bats to junior players to play them in, they both end up at the same end point.
Yep a bat that is larger in volume will hit the bat further but timing, bowling speeds etc all come into play. If you had the timing of Bradman facing the consistently fast bowling speeds of Michael Holding, what would people think of Bradmans bat shape! It would fly a mile that shape would be all the rage.
Concaving removes mass from the middle, if anything, so you get more bang for you buck if you have a flat middle. Edges do exactly the same thing, you are taking mass from the middle and whacking it on the edge...... Are we as really doing the right thing when making bats that have big edges and concaved......... So far this season I've done 1 out 10 concaved bat with a large edge, the rest all have been Flat middle with a slightly exaggerted edge and these bats are performing very well. Those profile I would say are classic shape bats with a twist.
Comparing bats that are drier [to the extent it creates a big bat] I dont think is a great comparison because it is not the norm even nowadays.....! Unless you are a bit unscrupulous or it has been requested!!!!!
