thats a fact.
in reality, the only difference is the amount of capital required. since this is limited to $20k, you can buy:
4545 shares of TLS giving divs of $636.30, with franking credits of $272.78
or
6666 shares of TLSCA giving divs of $933.24, with franking credits of $399.89
Thats an increase of 47%.
Both are likely to fall 14c once ex-div, so I hope you realise that a div strip's goal is to receive FRANKING CREDITS and not cash divs, since the capital loss and cash div usually cancel out.
While you are correct with TLSCA being the better deal, there are even better deals still. Look into instalment warrants and call options.
