Brakes off to brakes on is an excellent arrangement.
I find that resetting the parking brake after rotation makes for greatly reduced costs. Just remember to include it in your downwind checks, or the cost benefit can be negated quite severely.
For extra value, do your 'brakes holding' check at startup. Generally I find that at 1200 rpm, sadly they do in fact hold. However stretching to about 2,500rpm, there's generally enough 'give' for a very slow taxi out to the hold. Sure it takes time, but as this isn't costing anything there's no reason to hurry.
Ultimately this does not actually increase the 'out time' for the aircraft - the taxi back after landing tends to be considerably expedited, due to the fully failed brakes.
Wave knowingly to a blur of less experienced renting pilots as you pass their parking areas in rapid succession. Sometimes a taxiing 'go around' is required if you've got too much momentum. For small potential overrun, 'S' turns can help reduce unwanted speeds.
When you finally get back to the clubhouse, remark on the rather poor paintwork on the building behind the club's parking spot. Toss a fiver on the table, saying "and I won't ask about the change!" and give a cheery goodbye.
