So I have been looking around and it seems like if surfing is the primary goal, it is best to replace whatever factory ballast there is with large sacs. In my case I think I'll throw in an enzo sac in the port side and keep the factory ballast on the starboard or throw in a small 400lbs sac. The boat I'm looking at has just the two factory midship tanks (no 400lbs bow tank). I'm pretty sure that setup will deliver a good wake, but I've been looking around for some time and many people stress the addition of bow ballast to lengthen the pocket. The main questions I have are:
1) Is bow ballast useful in creating a nice surf wake behind an enzo sv230?
2) If so, how easy (and expensive) would it be to plumb a sac where the factory one would have been?
3) I'm not very useful at mechanics; could I get a dealer to plumb them in and install larger pumps at a reasonable price?
