I took the plunge and bought an msd 8383 dizzy and upgraded my leads for my 272 in an old clinker ski boat.   My question is this, does anybody recommend changing the advance curve from default standard to one of the other five available by changing the springs?  I know nothing at all about advance curves and also unsure if the default standard (2 silver heavy springs) is also alright for ski boat use.

The boat is only 4.5 meters long all fibreglass construction and the motor leaps her out of the water.  When in use the boat will go from idle to full open throttle to get going and drag the person out of the water then ease back when the speed comes up and hold on about 4000rpm for 32 mph. 

If it makes any difference the motor specs are she's freshly rebuilt, 20thou oversize 272, 4 barrel intake with a holley 570 street avenger feeding her. 

Any advice is appreciated as I thought it would be better to change now before I fit her into the motor.
