Have to agree with Oscar Duece here. I would think very very carefully about paying a dry rate. The only reason I was happy to pay a dry rate for my aircraft is because there is no mixture control, so no danger of other pilots over-leaning.
As for taking off as soon as possible, the easy way around this is to pay for take-off to landing (as my group does), or brakes-off to brakes-on (as the club/school that I hire from occassionally does). This applies for a dry rate as well as a wet rate.
