If you're happy with your bike light's performance (i.e. throw & spill) but would like to have it even brighter than an XM-L T6 could offer, then I think the best thing to do is swap the LED with XM-L2 U2s with copper MCPCBs like these at International Outdoors:

U2 is about 10 to 15% brighter than T6 and XM-L2 is about 20% brighter than XM-L so you should end up with a 30 to 30% brighter bike light. The copper MCPCBs would allow your LED to to perform better than stock aluminum MCPCBs since it allows the LED to operate at higher temperature hence decreasing the decrease in lumens due to heat.
