Is FST same as stock PU Sub Scorcher

I have an old PU Sub Scorcher I want to replace with a FST. But I swear I read something on the old message board or Matt's blog that he made some changes for the FireWire version. I can't find it now. Am I crazy? Anyone else remember seeing something similar?

The FST version is based off the Sub Scorcher Pro file rather than the standard Sub. It has a little more kick in the tail and no vee. It's also a 1/4" narrower than the stock PU dimensions.

Ride difference with no V and more flip?? Cheers

Well the V helps it to go rail to rail a little easier, but the extra tail flip would make for tighter turns on steeper parts of the wave.
I'd say it'd feel a little more stable in better waves but the PU version might wrap turns on a fatter wave a bit easier.
Not 100% in that though. You could always ask Matt Biolos the differences on his blog.

yeah they are close but prj has highlighted the differences pretty well.
