I've just purchased a 16" Stiffi Stif-Tip for my Freak back, and therefore have no need for my 14" gloss black freak front. I'd be willing to sell, dirt cheap.
I maybe wrong but I think the back section is a standard length of around 6", and my front section is 8", giving the total barrel length of 14". Someone more familiar with SP products could probably confirm this.
