I have cars with both set ups and in all honesty do not see the need to add the complication of pressure feed unless it is an original set up or you intend to use you car under exceptionally demanding circumstances. It is true that long distance races at sustained high RPM, such as existed at Brooklands, showed weaknesses in the jet feed system however modern oils and small modifications to the Jet set up negate these issues under most modern sprint and race situations.
