Hello,
I've been in similar contact with L&W recently with a view to getting a Reserve rather than a Sig. The clefts I was offered were very nice, but did not justify the price tag.
If I'm honest the two you have been offered are really lovely but they do not justify the price, or anywhere near it to be honest. Not to detract from them, but it isn't impossible to see a 'normally priced' bat with wood like that. I'd rate the grains on my new GT as being in the same league. Lets be logical, the grains are not perfectly straight, they are not perfectly spaced. The clefts are not 'perfect' visually, which is what I would want on a £300 bat, let along a £600 one.
Andy at Laver did tell me they are expecting a big willow delivery at the end of January and that if I was still interested, to check back then as he expected more choice then. He openly admitted that the Reserve clefts he offered me (one which had been originally graded as a Signature) were not 'earth shattering' (direct quote) and he could understand my reservations in choosing one of them.
If you are set on getting one it might be worth getting back in touch and putting that to him. Let's face it, for that kind of money you want perfection, otherwise you may as well buy 3 bats at £200 each.
To be honest these two were the sort of thing I was expecting to be offered for a Reserve. If I were to go for a Signature I would want it to look like the famous one shown on the forum which in my eyes, is 'perfect'.
