If you're looking to split tone then your bleach looks to be too strong. I usually use about 1+24 to 1+29 dilution for bleach when split-toning. This gives me ample time to monitor the bleaching in the highlights and whip the print out at the vital moment though even at this dilution I may only bleach for a handful of seconds. I then put the print under running water for a couple of minutes before toning. The best sepia kit I've found is the Foma kit (though it's re-badged by various other suppliers too). The tone in this kit is controlled by temperature from yelllow through deep brown. I find it easy enough to control even though I don't have the toner in a temperature controlled tray. You can see the effects I get in my gallery.
