Best bang for the buck

I have run SG for many years and used the exhaust evacuation system and vacuum pumps.
In fact I used a vacuum pump before they were for sale for crankcase evacuation.
I used a modified smog pump for years which worked very well.
With a vacuum pump you have less oil leaks and it does pick up horsepower. The horsepower is not that much and we throttle stop the engine anyway so a few horses is not a big deal.
I personally like the vacuum pump and recommend the Moroso units.
The crank trigger is nice but not sure of any major benefit other than it is easy to set the timing and does not move from the initial setting.
