I got some tubing in the mail today (don't know about sizing, don't feel like measuring and I most definately don't feel like turning the mm in inches), but I figure it might be too stiff. Hah, I put the tubing in the packer (without the nipple end 'cause those are at my other home) and the packer looks rather erect with the tubing. It will fold and stuff, but I'll have to see what it looks like with a harness in my briefs.
Fortunally I have the purple extensiontube that the whizz freedom sells as well. It's too short to use alone, but I might combine it with my new tubing, cause it's thrice and flexible.
