As far CA bat's are concerned in terms of durability and longevity. I have had nearly ten top end CA bats and only one broke at the end due to use which was solely due to terrible balls.
@roco Had a CA bat which was replica of Chris Gayle and what he used in Big Bash few years ago when he was with Sydney Sixers. I got it via Zahid Javed as I knew him.
I have gotten two bats from Nasir Jamshed and they were exceptionally good. Sadly, I did not retain any whilst I should have. Review;

As far AS goes, I had gotten one AS which was made for Aamir Yameen, fantastic bat. Blew me away as I was extremely surprised by it. Again, got it via Waqas Khalid as I know him. Review;
http://custombats.co.uk/cbforum/index.php?topic=36660.0Last month I ordered top end AS, whilst it costed halve of what CA would charge for their top end, but it picks up extremely well and has a great rebound. A friend is using it in higher division of league where Canadian national team players play.
I had also gotten MB LE directly from MB Malik via MB Malik's owner as I knew him (we haven't spoken in years now) and those bats were replica for Shahid Afridi in 2010/2011. Incredible bats. Review; Can't find it on CBF.
So, despite trying and owning all. I didn't have any bad experience, I don't know if it was because I had contacts with the owners etc. If they were dry, I don't care as they served me/us well so I couldn't care less if they were overdried or not.
